Is OTHER wrong in the post ? POST : First some background. 

When I was in highschool 2 girls liked me but I didn't like them back and nothing really  happened. Now I'm 5-6 years older and I still don't have any experience in relationships.Looking back I think I was taking highschool dating too seriously and should have taken more casual approach and probably fool around a bit and get some dating experience. I have a feeling I missed some things teenagers should go through.

Now I'm on verge of my 23th birthday. I recently met this girl and I'm pretty sure she likes me. We have lot of stuff in common and she seems pretty nice so far. She is 3 years younger. I'm not really sure I really like her yet and I feel like giving it a chance might help grow and experience relationships dynamics and who knows maybe dating will help me like her. So WIBTA if i started dating her while not being 100% into her?
