Cheating

I was with someone for about 6 months and I fell in love with him , he is perfect for me. One night I get a call at 3 in the morning and he’s freaking out drunk telling me he fucked another girl & how sorry he was and he regrets it and I was devestated. I stayed on the phone with him till he got home (he was driving drunk!!!!). Anyways this shattered my heart considering he knew I’ve been cheated on before. Honestly it’s been MONTHS later and he still tries everyday to win me back. I truly believe he regrets hurting me so much. And I truly truly believe he wouldn’t ever hurt me again. He’s literally obsessed with me and I’m still so in love with him. I just need to know if it’s worth giving him another chance because I honestly see a future with him. I feel like you just know. Have u guys gave ur SO another chance and it ended up positive?
