I saw my wife with another man in the parking lot. I have a video.

I (34 male) have been married to my wife (33 female) for 10 years. We have a 7 year old daughter and a 1 year old daughter. My wife is very attractive. I was already attracted to her before she was my girlfriend, and I attracted to her even more now than I was then. I love her to death. I have always been faithful to her, and I can't imagine cheating on her now or anytime in the future.<br><br>I am extremely sensitive to cheating, though, because I've been cheated on in the past. My high school girlfriend cheated on me. A girl from college I was dating for 2 years cheated on me. Even though my wife is the most trustworthy person I know, I still get nervous about cheating, just because I've been hurt so bad by it before. As a result, in the past, I would get a little nervous even seeing my wife talk to other men. At one point, my wife told me she didn't like how I reacted to her talking to other men. I said it was because I have weird insecurities about cheating. She told me that she never cheated on me and that she never would. I believed her and I trust her 100%. I have zero evidence that she's ever cheated on me and I believe she loves me just as much as I love her. Every single day I'm grateful to have her in my life.<br><br>Well, I was in a parking garage this weekend and I saw something. There was a couple in a parked car, and the garage had a mirror to see around a pillar, which allowed me to see into their car. They were being very sexual, but I don't think they realized anyone was watching. They were in the front seats, but they saw me in the mirror. They didn't really react. I figured it was none of my business. I parked and went on my merry way. About 2 minutes later, I saw the man, and it was my neighbor from across the street. It was a complete coincidence, but he was walking by me on the street, and I hadn't seen him in a while, so we exchanged pleasantries.<br><br>I didn't think much of it. Maybe he was with his wife. But when I got home, his wife (D) was mowing their lawn. My wife said she was going to the park with our daughter, and she invited D to come. D told her she was going to be home all day doing chores. Then, my wife and daughter left for the park, and I decided to look at the video again. I enhanced it, and it wasn't his wife. It was my wife. It was unmistakable. I recognized her jewelry, her hair, her handbag, and I'm 100% sure of it.<br><br>I have no idea what to do. I showed the video to my wife and she broke down. She apologized profusely, and said it was with a former boyfriend from a long time ago. She said he was in town and they hooked up and she never intended to and that it meant nothing to her and that she loves me more than ever. She said she wants to go to therapy to work through it and she wants to do couples counseling and she was willing to do whatever I want. She's been crying nonstop and begging me to forgive her.<br><br>I don't know what to do. I love her so much. I want to forgive her. I want to believe her that it was a mistake and that it meant nothing to her, and that she loves me more than ever, and I want to move on from it. But I keep imagining her with him and I can't get it out of my head, and I feel terrible.<br><br>TLDR: I video recorded my wife hooking up with another man. She apologized and says she wants to work through it in therapy and counseling, but I can't stop imagining it.
