my name is yasmin i have a question to ask and i need a quick reply please

do i still love him or i just need sex ?!
year ago i me THAT guy the one i loved the most and he became my boyfriend very fast
we broke up after about two months
i was terribly broken and so lonely and sad although i knew after we broke up that he is just an asshole but i didn't meet any other guys til now i don't like anyone of them really !
any ways we broke up because some family problems ( my family ) he didn't stand by my side he didn't support me he just walked away ! AND he got back to his ex week later
i know it's obvious he didn't love me although i felt he did
anyways after about a month we talked again just like friends he told that we can be friends but we won't get back together i thought it's ok because all i wanted is to be around him
during that time he broke up with his ex then he got back then broke up again like 100 times
she didn't know that i was talking to him behind her back
and the thing that happened alot is without any reasons he stopped answering my calls then i call him after a while and he answers that happened alot too
but 6 months ago we had that sexual experience it was my first i went to his house and we did it it wasn't real sex but we did take off our clothes but he didn't break my hymen when i was on his bed i asked him to get back to me and he quickly said yes but he treated me like bullshit after that day and we broke up month later and again i was terribly broken ,
since that time we phone sex almost everynight but we didn't do it again we didn't meet on person
but now the problem is sometimes i feel like i don't love him anymore i did suffer alot i don't know if i love him or i just want to have more fun with him !
we're not even in a relationship but we phone sex everynight
and do u think that he loves me still !
or do u think i even mean anything to him

i care about him alot but now i'm really lost i feel like i'm empty inside the day i don't talk to him please i need a quick reply btw i'm 17 and he is the same age as me
sorry for the long topic but i really need the answer that may sound silly but i can't even sleep ! and sorry if there's any grammar or spelling mistakes in my topic i'm not THAT good in English
