Am I not good enough ?

I am in my 20s and it seems like all the guys I know only wanna hook up nothing more. I’ve known a few of them throughout college and some nights we will be flirty and such but instead of ever asking me out they just ask if I can come over for the night or even a few hours during the day. It’s really making me have low self esteem. I’ve spoken to my close friends about it but they say it’s just boys being boys and to get over it I’ll find someone better. I have feelings for one of the guys that treats me this way and he’s told me likes me too but he keeps treating me like I don’t matter and I am an object. What should I do ?
