Relationships

Okay girls I need some advice. I’ve been talking to this guy for a while, we’ve gone on 2 dates and he’s a great person but last night I started doubting it, I’ve felt like this when I woke up so I decided to hangout with him for the day, I still felt like it was all wrong. Like I shouldn’t be in a relationship with him. Now the weird part is I always feel like this with the guys I’ve dated, it’s perfect for a few days then it just crumbles down. I just thought that maybe I’m lesbian. Maybe I’m afraid of commitment, or maybe I just don’t belong in a relationship.
