i dont know if that is a reason to run

i started to see this guy and on the first night i ended up staying over we didnt have sex we spent the whole night cuddling and talking and getting to know each other. it was kinda perfect. the next morning he wanted me to meet his friends. i made a joke about what if i wanted just a hook up and he could tell that i wanted more and he expressed he wanted more. a few weeks went by still seeing each other everything good. we never had a talk if we had a label or not. one day i was at his house and i toke a goffy picture of him and said look at this butt face. and he said " are u telling ur friends that i am being a bad boyfriend" so that was the frost time he said that after that point i thought of him as my boyfriend as he said this more times after that point as well. he also at this point had me meet his mom. witch felt a bit soon but i really liked her and it seemed she liked me. i am not a highly trusting person but he really wants me to open up to him and trust him and he trys so hard to make me feel like i can ( i have a lot of truma) so before me he was dating this girl for 4 years. i dont really know how long they were apart before he started to see me but i dont think it was long. beacuse one day when we were hanging out with his friends and one of them saying" ya two Saturdays ago we were scqred to let him drink due to the recent break up" and that was a week after we started to talk. also one night we were just laying in his bed and talking about everything under the sun his snapchat notation went off and it said princess Jacky. and that is his ex's name the name kept going into what i think was 💝 that emjio but i was so shocked to see the word princess. right now i am at home with my family for my thanks giving break i was face timing him and was asking me is i saw a old hair cut that he had told him that facebook said i should be friends with him. and he laugh for what was like 45 seconds then asked what i though of the pictures of his ex. even though he is so amazing and i think i could see myself trusting this mab at some point down the line it is still worry some that after he called himself my boyfriend meeting his mom and friends he still has his ex saved as that. now yes it could be the name that username came with but he has edited every other name so it seems unlikely idk i just dont know how this all makes me feel. i know he isnt a cheater but i cant fight some feeling that he will end up breaking my heart
