A while ago he texted a girl behind my back and then i found out by accident when i was on his phone getting families numbers. Meaning he never even intended to tell me. Also i found out on our three year anniversary so that’s convenient. Then like it’s been a while since i found out and everytime i ask questions or say anything it turns into a pity party for him. i don’t understand why he did it and everytime i ask him why he says i don’t know. then to top it off he turns around and has trust issues with me for no reason but being insecure. I just need advice and help please!
