Advice please!

basically i dated this guy for 6 months and i couldn’t never go to his house bc it was under renovation and never met any of his friends or family. He would always need to stay at my house when we saw each other and this was only every sunday, sometimes not even that. Also sometimes not even for a sleepover. He only ever asked to call me once and we never facetimed. he would always get really upset that i didn’t show affection with hugs and kisses and holding hands, but this was bc he was my first bf and i never saw enough of him to get that comfortable. i hadn’t even met his dogs and i asked him why and he said bc i never asked. he always spoke about his friends to me but i never spoke to them or met them, even on social media. he only ever posted me on his story on ig once but not a post and didn’t make me a highlight. i broke up with him 4 weeks ago but we’re still friends. he bought me a £92 skateboard for my birthday as well. i regret the breakup bc we were really cute together but he never actually felt like my bf… but the sad part is if he showed me off and had more time and stuff and was more empathetic and understanding towards me we would have worked out so well. also i told him to stand up for me if someone was being disrespectful towards me, one of my friends, but instead he said “she told me to stand up for her but i can’t with that one cause ur right”. i just never felt like he took me seriously. also when i broke up with him he told me that he used to see me as his future wife but recently saw me as the closest girl he had that he could have sex with… but later told me he only said that cause he was angry. i’m thinking of telling him that if one of us gets into a new relationship we can’t be friends anymore, bc it’s really hurting me staying friends with him bc i still have feelings and it’s sad talking to him like a friend and him calling me “my ex”. basically i was upset with him that he didn’t stay with me in the apartment on valentine’s day, i went clubbing the previous night but as i was on my period i was feeling tired so wanted to stay in the room, but all he said was “im going now” and went clubbing with his friend and i overheard them all tell him he should get with someone at the club and he apparently agreed. bc i wasn’t talking to him much the entire time we were on the trip bc i had anxiety and was in pain and he didn’t really speak much to me either. when i told him about this he said the plan was to go clubbing and he wanted to experience the place and have fun and that i could have gone if i wanted to. i guess im sad and angry but he’s buying me an expensive gift and he is really sweet and messages me and stuff, but tbf he doesn’t really ask about my day anymore, only i do, since we broke up. idk what to do really. Could someone advise me, thank you.
