AITA for not inviting my brother to my birthday?

I f33 m44 and I'm in a long term relationship with my partner. We've been together for over 10 years. My birthday was last week and we decided to spend it with my family.<br><br>My brother and his wife do not get along with my partner. They are very religious and have a hard time accepting that my partner is homsexual. They think it's a "choice" and a "sin" and that if I "prayed harder" I'd find a girl. I've tried talking with them several times about this but it never comes to anything. <br><br>For my birthday we went to my parent's place and they made celebratory food, bought me a cake, and gave me a nice watch. My brother and his wife also came.<br><br>Before they got there my partner excused themself to go to the restroom, and when my brother and his wife came I said "Oh you're just in time, my partner is in the bathroom and will come right out. I'm sure you remember them, we've been together for a very long time," and they looked at each other and my brother said "We thought you'd broken up."<br><br>I asked "Why?" and he said "Because you know how we feel about it," which was something they'd said before, that they wouldn't acknowledge my partner unless I broke up with them.<br><br>So I said "Then you can go now," and they looked at me, shocked, and my brother said "No, we came because we thought you'd be single again," and I repeated "You can leave now," and my brother argued "We're here now, we've driven all this way," and I said "You can go now," and he looked at our parents and said "Father, mother, is he kicking us out?" and they didn't respond, just kept looking at the ground and clearing their throats.<br><br>My partner came out and my brother and his wife left. During dinner I asked if they were okay with my partner being there and they said of course and I apologized for not telling them about it sooner. They said it wasn't a problem.<br><br>My brother called me up and told me I was being "petty and vindictive," and I said "No, you were the one who didn't invite my partner to your wedding," and he said "That's different, this is just a normal family gathering," and I said "No, this was my birthday. You didn't invite my partner to your wedding and you didn't invite them to my birthday, and when you came you said you thought we'd broken up." He said "I didn't say that," but I said I'd recorded him.<br><br>He sent me screenshots of text messages with our parents, from before the party, saying they would not attend if my partner was there and my parents replying saying that it was my birthday and I got to decide. <br><br>He said "See! You lied to me," and I said "I didn't lie. I said you would not be welcome if my partner was not welcome. I'm sorry, but you cannot exclude my partner," and he got angry and called me a "terrible person."
