im confused and need help

so last night my friend and i were talking and i feel like he took advantage of me. he always asks me for nudes but i always say no then he ends up convincing me to send bathing suit pics to him. after he gets them he keeps trying to move farther but if i dont allow it he’ll stop texting me or tell me he has to go. yesterday i was texting him and he was heating up the conversation, im not fully saying it was all him i was heating up things too. then he started asking me questions like how horny are you and how wet are you and ended up seducing me in a way. then he convinced me to facetime him and masturbate with him while on facetime, he didnt see anything though. after if happened he went straight to bed. he didnt text me or anything. i texted him this morning and he started texting me but only about last night. i told him to switch up the topic and he said idk how and said im gonna go. so he stopped texting me because i told him to stop talking about all that stuff. he is a fun dude to be around and i really do enjoy hanging out with him but it just feels like he takes advantage of me all the time. he also asks me about giving him head or fingering me and giving me head. on top of that he shows no interest in really getting to know me better or like even dating me. i feel like hes just using me for my body. can someone give me some advice on what to do.
