<human>: So there's a girl that I like, and I'm pretty sure she likes me. We've been hanging out, talking, and we've been like this for several months now. I don't want to remain just friends like this, and I think she might want me to ask her out.

However, I don't feel like I'm ready, or that I'm able to move into a relationship because of my past. Back then, I liked 3 girls (different times) and neither of them worked out. Furthermore, people still tease me about one of the times where I was "chasing" (looking for her love). Everytime I think about a relationship, I just feel uncomfortable and fear. Essentially, everytime I've liked a girl, I got my heart broken, disappointed, and lowered self esteem.

I like my relationship with this girl now, but I'm not sure what "asking her out" entails and if I'm ready. Even if I knew, I probably won't be able to.

Do you guys have any advice for my current situation? Should I tell her about this? Or should I just ask her out and try to work with it.

Give me the gist of the text in a nutshell
<bot>: I like this girl and I'm sure she likes me back. I'm scared of a relationship because of my past experiences with girls. What should I do?
