Confused

Sometimes I have a hard time seeing my own worth because I feel like the people close to me constantly take advantage. I've been seeing someone as a fwb type situation for almost 2 years now. In the beginning he's saying he wants a relationship with me, the time just isn't right. Now he's made it clear he isn't looking for anything serious but yet he sees me just about every single day to just hang out, not even looking to hook up all the time. Because of him, I'm starting to feel like I'm not good enough and that I won't ever be good enough for someone to want me as a real girlfriend or wife. In the beginning I communicated my feelings to him but now that he has said he doesn't want a relationship, I just hold my feelings in. This guy messes with my emotions so much and I just don't know what to think anymore. I want to stop feeling this negative way but I really love him and don't want to walk away.
