<human>: This is LONG so bear with me. I'm 22 (F) and he's 22 (M). We've been together for a year.

So I'm the one that fucked up our relationship by texting my ex with flirtatious messages (nothing sexual, but emotional and insulting my bf? yes). I did this for two days when things were really bad between my boyfriend and I, which was incredibly cowardly, but I stopped cause i genuinely felt bad about it. Nonetheless, my boyfriend was snooping through my phone one day and read the messages. We broke up because of it but got back together. I texted my ex three months ago and my boyfriend and I have been together for a year. But since that incident, he has become a complete asshole that is constantly insulting me by calling me immature, stupid, and slutty. I know a lot of you probably think the relationship is completely broken because of what I did, and we're just prolonging a relationship that can't be fixed, but I genuinely love him and wanted to spend the rest of my life with him. However, since we split and got back together, I'm really depressed.

I've tried talking about my feelings with him, but he dismisses whatever I say because I 'owe' him for what I did, so whatever problems I'm experiencing in our relationship, his problems are worse. The reason I'm writing on this forum is because I'm wondering whether any of you have gone through something similar, and how you regained happiness in the relationship after screwing up.

Give me a shortened version of the text
<bot>: have any of you made a mistake in a relationship and then became depressed? If so, how did you become happy again?
