Should i feel weird about this?

So i went out with this girl a year older than me when i was a freshman.She was my first girlfriend We were togther for six months and then we broke up. I really had feelings for her and she broke my heart. months passed and i went out with another girl. My ex-girlfriend and current girlfriend back then were close friends. it became a big mess cause they fought over me. Then me and my second girl friend broke up. More time passed and i fought out my first girlfriend was lesbian and was going out with this girl and they broke up. Even more time passed then i found out my second girlfriend was lesbian and was going out with my first girlfriend. I dont hate gays lesbians or anything else. But Im straight and always will be. These have been the only relationships ive been in and im going to be a junior. It makes me feel so weird that this happened to me. Will these feelings and weirdness go away. I feel like i've never been in any real relationships since they were basiclly lies. What should i do? How will i get over this?
