Relationship advice

Hi everyone I'm trying to get some advice on men/relationtionships. I'm 23F and have never had a boyfriend before. I've had several situationships and I'm just struggling on how to move forward because it feels like no matter how hard I try with men it never works out. The men I have taken to in the past have presented as very nice guys gentlemen, however I feel like they love bomb me and then suddenly lose interest. One previously just ghosted me and then kissed another girl in a bar in front of me, the second said it wasn't good timing that he just wasn't ready for something serious at the time, and the most recent stated that the distance (2 hrs) was too much for him and he didn't think it would work out (even though I drove to him each time I saw him). I'm just feeling hopeless about dating or ever finding someone that will love me. I have plenty of interest on dating apps and get matches that I cannot even keep up with. But I just don't know what I'm doing wrong or if there is a way to weed out these kind of men before I even meet them.
