7 months into our relationship he begins to breakdown, repeatedly tells me he is drowning in anxiety and feels overwhelmed. He goes out one night and gets blackout drunk and high and makes out with another girl. They did not do anything past makeout. He didn’t tell me but instead broke up with me, crying. He told me he didn’t deserve me and that if he could have had anything it would be me but he fucked everything up. He asked if for a month he could have space to try and get his shit together and better himself and I said okay but once he his in a better state mentally we HAVE to address what happened and make changes. We are currently on our ‘break’ right now and I’m so afraid he is going to go with a different girl again. Is this forgivable?
