Abby

so for the past 3 months, me and a guy from work that is 11 years older than me have been fucking and one of the first things he said to me was “don’t fall in love”. At first it was strictly fucking and then we started to go to the movies, he took me to a fancy steakhouse and spent $200, and we’ve gone out to lunch a few times. I have a billion clothes at his apartment and he bought me a toothbrush and shampoo and different things to keep there for when I️ stay. he is super straight forward about everything and wants to “teach me something” about myself and wants to show me my worth because in the past I’ve let guys use me because I️ think they actually care when they clearly don’t. so about two months in, he started saying things like “I️ know you’re falling for me. And maybe I’m falling for you, too” and we wouldn’t talk very much about it but it’s clear how I️ feel about him. 3 weeks ago, my mom went through my things and read my journal and found out about him and freaked out and I️ told him what happened and ever since then we haven’t hung out very much but when we have, it’s been fine, like nothing ever changed. This past week and a half, he started be more distant (and let me remind you we haven’t gone more than 8 days apart for the past 3 and a half months) so i questioned him about it and he said that he’s just been going through a rough patch and he isn’t the type of person to open up about much so I️ didn’t pressure him into talking to me about it. But he was like “have you been fucking someone else since we haven’t seen each other in awhile” and I️ was like “no, I’m not doing that unless it’s someone I️ actually care about” and he just kept going on about how he hasn’t been going out with other girls or anything, it’s just him going through stuff with his family and he’s sorry for being so distant. And then when I️ said that I️ wanted to see him soon he said that he’ll “try”. He’s usually super straightforward about things so I️ don’t think he is trying to cut ties because he would just come out and say it but idk what is going on in his head and I️ want to help and I’ve told him that and that I’m here for him but I️ just don’t know what else to do. All he does is go to work and go home. He used to go out with his work friends to the bars and have fun but lately he hasn’t been like that and I’m worried. someone please give me advice. I️ don’t want to lose him.
