Hopeless😔💔

I always get my heart broken, every guy I date ends up hurting me. I try to choose the right guys... They are right from the beginning but then they change in the end. I just got out of a controlling relationship yesterday... What am I doing wrong. I feel like something is wrong with me... I don't want to end up alone. I want to be married and have a family :( but I feel like it will never happen. I'm only 20 but ever since I was 17 guys just hurt me so bad I feel like I will forever be alone. What's wrong with me :( what do I do... ?! I cry so much at night because I don't want anyone to see me cry... I keep myself together until I'm alone and have time to straighten myself out... What do I do? :(
