My boyfriend (29m) thinks I'm (21f) covering for his best friend's (30m) cheating girlfriend. (20f) But I wasn't. I just didn't recognize her face when I walked in on her and my roommate.

I am in a relationship with Nick and have been since freshman year of college. Nick's best friend is Alex, and Alex has a girlfriend named Lia. I've met Lia a couple of times, when the boys are hanging out and she and I come along

It's worth mentioning that I have a terrible memory for faces, if I see someone out of the context I usually see them, I don't recognize them. Unless they've got some distinctive mannerisms, or I hear them speak, or they're wearing something distinctive.

I live in student apartments with 15 other people. One of them is Bob. I'm not really close with him, were just in the same building.

One night last month, I walked into the laundry room and saw Bob screwing a girl on the dryer. I was just like "ewww take that to your bedroom." The girl was staring wide eyed at me, but I thought that was just her being shocked at getting caught. They both looked shitfaced drunk. Like the girl was really sloppy, hair all over her face, her dress was hitched up super awkward around her neck

A few weeks later, I walked into the house and saw Bob making out with the girl on the sofa of the common room. I snapped at him to take it upstairs, I didn't want to see that.

Just this week, I heard from Nick that Alex dumped Lia because she was cheating. I shrugged that off. Then Nick asked me if I'd actually seen it happen, because apparently when Lia got caught lying she told everyone that I'd known about it for a while and never said a thing.

I said no.

Nick said that he'd heard I'd walked in on her and Bob in my house. And then it clicked that Lia was the girl that Bob was screwing in the laundry room and making out with in the living room . I explained that yeah I did see it a few times but I didn't recognize her. And Nick just doesn't believe me, he thinks there's no way I saw a girl I knew in my house a couple times and didn't make the connection. He told me that it changed the way he saw me, that I'd ignore something so shitty instead of speaking up. And lie afterwards.

I honestly don't know how it didn't click for me. But it didn't. And it looks like I'm lying. How can I explain things to my boyfriend?

tldr - I saw the girlfriend of my boyfriend's best friend cheating, but I didn't recognize her. My boyfriend assumes I did recognize her and was covering it up
