girlfriend runs to another guy
my girlfriend (18) and i (19) have been together for almost a year now. i honestly have no idea what to do anymore. to keep things short, back in april we had an argument and broke up, the argument was my fault & i broke up with her for no reason really other than my own unresolved abandonment issues. we didn’t text for a couple hours after but later that night we were texting again & hung out the next day. that day though she was on her phone and got a snapchat notification that someone added her back, the person who added her back was someone she has slept with before me. she tried to make excuses that he just randomly added her back & he didn’t add him the night we broke up. but her whole argument was “we were broken up” so it’s not like she cheated. we were broken up for less than 5 hours. she doesn’t see the fact that it was so quick for her to want somebody else.
about 2 months go by and obviously i don’t trust her like i did because of that. she blocked him & we were starting to move past it. but in the end of may we get into a little argument again, we didn’t break up but we agreed to take a couple hours away from texting each other.
last night i looked at her recently added on snapchat because i had some weird intuition & what do you know, she unblocked him when we had that little hiccup in the end of may.
i can’t believe im still talking to her right now & honestly im disgusted in her behavior. she says that she adds him when times get rough for “validation” and because he’s “easy” and will give her validation instantly. i have a strong feeling that she wants him but is with me for whatever reason, i also don’t want to be with someone that runs to someone else when things get hard. i honestly can’t believe im still in contact with her but she begged and begged for me not to leave. like i said i dont want a girlfriend who wants someone else but i dont know what to do anymore. any tips?
