<human>: Not sure what to do or if there is anything I can do but my boyfriend of over a year broke up with me around March. I wasn't as broken as I thought I would be, plus my friends really helped. Sometime late May, after I had been with a few other guys, not to mention I was involved in a threesome, ex-boyfriend starts texting me to hang out and everything. I only think this is more of a bootycall type of thing but to him it's something else. He goes home for one day and I ended up being involved in a half-assed foursome. He finds out and becomes incredibly angry and upset and feels betrayed. I feel like an asshole a little bit, but I don't really think it was an act of 'betrayal' as he thinks it is. I couldn't catch up on the subtleties that he's trying to get back together. He didn't make himself clear at all am I wrong for not assuming that that was his intention? Anyway, he's still hung up on it and I love him a lot but I don't know what I should do. He thinks I'm cheating and I would never do that. There's a lack of communication and directness that's missing that I have at least been trying to work on. I don't think it's not anything fixable but I don't know where to go from here.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Boyfriend found out about a foursome I had while he was apparently trying to get back together with me and now thinks I'm cheating.
