So my GF in college want daily compliments and stuff blah blah. But I hinted her lot of time that I also expect same. She didn't in the end, and I felt frustrated. My female friend used to compliment me, I followed along. Later, we secretly slept together. Following this, my female friend told my girlfriend to leave, claiming she is now my new girlfriend. Now my girlfriend is crying and calling me a cheater and somewhat I regret from back of my mind. Honestly, what should I do?

EDIT - My female friend just not compliment me one day, but she is doing things from way before for me, helping and stuff and everything whereas my GF was way different person.

EDIT 2 - People who are blaming me, I know cheating’s wrong, and I feel bad about it. But for months, my girlfriend’s I’m “lucky she’s still around. When I told her I felt unappreciated, she laughed it off. My friend wasn’t just a compliment. she’s been there for me, listening when I was falling apart. I messed up, but after my girlfriend ditched our good moment picninc for her friends, I felt bad. Now she’s the victim?I regret it, but I don’t know if I can stay with someone who makes me feel invisible. AITAH?
