It was recently my birthday (I can legally buy booze now, which I definitely need), and my ex sent me flowers and chocolate with a card. The card said "I’ve been thinking about you a lot… and I'm sorry. I wasn’t listening to what you needed, I was too focused on what I wanted rather than what you were telling me, and I regret that. I won’t try to reach out again, give you the space you need, but if you call me, I'll answer."
I haven't talked to her in almost 2 months, but I miss her and kind of want to get back together. Long story short of it is, she's my first girlfriend, she got me into chastity, we've been dating for a couple years, recently she'd been wanting me to get fucked by a man, and we had an argument about it. She was hinting at it, making references to it while we had sex, we'd watch porn where that was a feature, she'd point out 'cute men,' etc. I don't find men attractive, and the idea of being with another man makes me uncomfortable, so I'd been hinting back that I wasn't interested, before finally flatly telling her I wasn't attracted to men and asking her to stop. She did, for about a month? and then she started again, so I blew up on her. I called her out for not respecting boundaries, and told her I needed time to cool off, or that we were done, or something like that when I left. Anger makes it hard to remember, I just remember me yelling, a lot, and leaving.

I don't have much experience with relationships; literally just her, so I don't know if I should I just keep pretending like she doesn't exist, or if I should call her like she asked me to. I know 4chan is among the worst possible places to ask for relationship advice, but considering the nature of the argument I'm not comfortable really asking anywhere else. I mean, an AI maybe, but... I don't trust that.
