romantically lost

i 21f have been seeing this guy for abt 3 months, and today he called and told me he thinks it would be best that we’re just friends. for context he lives about an hour away from me, so we dont get to see each other as often as we’d like. im not even mad at him or anything, im glad he was honest with me. i just feel like theres something wrong with me that makes people not want to commit to anything with me. my last committed relationship was over two years ago and only lasted abt 3 months. she broke up with me which was something i wasnt used to. ive had well over 10 relationships in my life, and ive always felt that im worth being loved. ever since i turned 18, ive been struggling with dating. it just feels like sex is all people want from me, so i feel like i have to provide that in order to be wanted. i like to think im a good person.. everyone in my life says im deserving of love but how am i truly supposed to feel when the love i feel for people isnt reciprocated ?… im just very, very lost right now, and im losing hope for myself. i feel very unlovable. besides my dating life everything is going to shit so im not in a great place. my friends and family are here for me which im grateful for. i would just really like some advice on what i should fucking do with myself.
