AITA for making a fatherless child cry or is it the other way around?

I (33m) recently got an invite to a family wedding. I used to go to the same school as the groom and we were good friends. I haven't heard from him in years and the invite to the wedding seemed to be addressed to me and my wife under the brides name. It made me think that maybe they decided to send a generic invitation to all the groom's school alumni or they might have found all the addresses from facebook. <br><br>Anyway, my wife and I decided to go to the wedding because the venue was a very nice hotel and we did miss the groom. He and I used to be in the same circle all the time and I missed him a lot after he moved away. I don't know why he never tried to contact any of us when he moved to the other side of the country. Maybe he felt awkward or something idk. <br><br>We decided to book a room at the hotel and stay there for a couple of days. I got very excited about seeing my friend again and decided to bring a gift for him. Two days before the wedding, I got a text from the number I sent RSVP to and said I need to cancel my reservation because my friend was worried his wife will get upset. Apparently, she doesn't like me because she thinks I'm a bad influence in general. This was what caused him to move away and lose contact with his old friends. <br><br>In short, I was a typical student and I liked to party and have fun. The groom wasn't any different. He had a girlfriend but things started to go wrong when I got invited to parties they went to as well. They would wonder where I was and not notice my friend until later. I had a girlfriend too (who's now my wife btw). So the four of us would spend some time together in the same circle and the girlfriend would seem disappointed or upset and because of this they didn't get invited to any parties we were attending. Maybe that was a little humiliating and they started to resent me. <br><br>Anyway, I texted back and said I already paid for the room and won't give it up. My friend could do all the explaining he needed and I did say I don't give a shit if his wife doesn't like me. I apologized to him if he had to do something uncomfortable for me. He agreed without saying anything and I assumed he understood. <br><br>At the wedding, the bride seemed totally stunned when she noticed me. I didn't know whether I should let her know I was there or just leave her be. I decided to let her be and just kept my distance when I saw her coming in my direction. She came up to me and asked me how I dared to show my face there. She also told me that the groom asked me nicely to cancel my reservation and I refused and insisted on attending.<br><br>I turned her down and told her I wouldn't budge without a refund and she should've tried to contact me herself. The bride told me she was sorry but I could only have the refund if I left right away. I refused and said I was going to stay until the wedding was over. The bride asked me if I wanted to ruin the entire wedding and I said I couldn't care less about the wedding especially since neither the groom nor the bride invited me in the first place.<br><br>Really clueless woman asked me if I knew how my presence made her groom feel. I told her I didn't give a shit about how he felt. She started to talk about "the fatherless child" and asked me if I knew what it meant. I thought she meant her maybe but I was sure she was indeed the fatherless child since she was a single mom.<br><br>I told her I didn't know what she meant and she said "I am a fatherless child and I know exactly how your presence in this wedding made my husband feel. I am a fatherless child and this is how it feels. Now you know how your friend felt." As I was still confused about what she meant, she took my arm and led me to where the reception was taking place.<br><br>As we reached the reception, all eyes were on me. I really wanted to leave at that point but I decided to swallow my pride. One thing was standing out though. The bride's son was standing right behind her and he looked about 4 years old if not more. I had no idea the groom was married to a single mom when he first got involved with her.<br><br>The groom noticed me and started to walk towards me. I told the bride I completely understood what she meant now and I really was stupid for not realizing something like that. The groom looked like he was in disarray. I told him I really did apologize. I never meant to hurt him. He told me he forgave me when we were in high school and we were okay. I said it was okay but I would like to apologize again for my mistake and that this was the perfect opportunity for it. The bride said "See! There's your apology. Are you satisfied now? Can we please ask you to leave?" I agreed and apologized to everyone and left.<br><br>Last night, my wife told me the bride was blaming all this on me in her social media post. Apparently, she said I forced my way into the wedding and caused a scene by asking her about her son's father in front of everyone and I was going to get into a fight with the groom but one of our classmates calmed me down. I tried to stay calm and not comment on her post but it was making me very upset. My wife suggested that I wouldn't care about it if I didn't know deep down that I was indeed an asshole. <br><br>She said I was a little asshole back in the day but I grew up and became a better person and I was still in denial. She said I would feel better if I just agreed and promised not to do something like that again. I refused but my wife still thinks I was in the wrong.
