recently on friday, i found out he hung out with his ex, who is his neighbor, a few times because i saw a heart next to her name on his phone. he said it was no big deal and that she put the heart there and all that. so friday night we had a huge talk about everything and he apologized and i forgave him and we were fine again. that's not the problem right now. saturday i didn't really talk to him at all and we didn't hang out so i was left alone thinking... and i started to think about everything and sunday comes, and he comes over. i told him we need to talk and we took a walk and i tried to talk to him about the whole issue we had on friday. turns out i really didn't need to talk to him about everything because that just made him upset. so we get to my driveway and he goes into his car and he won't come out. i'm standing there asking him to come inside or something and he won't and then i get upset. i start crying and i end up having a panic attack and it's around 6:30 pm and he says he needs to go. and i KNEW he was lying so my big sagittarius mouth says you're a liar, you're lying. and earlier when i was trying to talk to him, he kept playing around with me physically like poking me and stuff trying to make me stop talking i'm guessing? and i got mad and when i get mad i just say random things. so anyways, it didn't end well. he yelled at me and i broke down crying. and then he left. today we talked and he said he doesn't trust me and he never did. that really hurt me. he also said his apology didn't mean anything to him since yesterday i was trying to talk to him about it again. i wrote him a huge text message telling him how i feel about him and all this, and his reply was "I just need to take a step back and think about things." & btw, we've been dating for almost a year. and i'm a sagittarius sun, moon in leo, rising in gemini & he's a cancer sun with a moon in sagittarius. help?
Why was he hanging out with his ex at HER HOUSE?
Why was she going through his phone?
What on earth did he say about this?
