I found my gf cheating, wanted to break up but I'm genuinely hanging on because of her dad
I'm a 21 years old guy, and I've only ever dated this one girl. I met her freshman year and we've been dating ever since then. We hang out a lot and would come to each other houses sometimes. College got a bit busier later, so I focused more on my studies and slowly spent less time with her since then.
Last week, on a Saturday afternoon when she hang out at my family's house and we were playing video games with each other, she forgot her lipstick at our place when she left. After dinner I drove to her house only to find that she had left for dinner. I asked her mom and dad and they said she told them she was going out with her friends. I was planning to just drop the lipstick at her house but her dad told me I could drive there and wait to take her home if I can since she got picked up by her "friends" and didn't drive.
So I did, I went to the place and waited for like, 15 minutes, then I got impatient and went in to check if she had already left. What I found? She was eating with this guy and acting real intimate with him. I just didn't have the courage to confront her and I didn't want to make a mess and fight in the restaurants so I just drove back to her house crying. It was the most I've ever cried, I was faithful to her and only ever loved her, I felt betrayed and like I lost something really important. I wanted to blame it all on her, but in my gut I still felt something like what if she got bored of me because I wasn't paying attention enough to her.
Now, I'm pretty close with her dad. He was a really nice guy and was hospitable to me when I first got introduced to him. Sometimes I helped him fix stuff up or build things around the house, and he would treat me to a drink. It was all very fun times. I guess growing up, my own dad wasn't really emotionally present so it felt nice to have someone like him in my life.
When I told him all about it, he was very supportive. He didn't blame anything on me and said he would ask her clearly about this. He also said that he thought I'm a great boyfriend, and she cheated on the wrong person. Even though he didn't force it, he asked me to give her a second chance, and that she is "young and still dumb".
I went home and the next day, their parents called me saying they scolded her and that she really was cheating. I think they scolded her big time since she texted me with a really apologetic tone and said it was a "mistake".
I don't know if I can trust her words, since she could just be saying this because of her parents. Then again, whenever I think of her dad, I'm uncertain of breaking up. I think it's a mix between not wanting to be on bad terms with him and feeling bad for him if I leave her. I just feel so messed up in all this.
Dinner is a simple Pizza.
