Don't ever enter a relationship with selfish expectations.

You may have things in common, good. Even if they are bad ones.

Don't push things. Do you want a potential true friend or just a lover? That's your choice.

Sounds like you want more than what she wants.

Don't live in bubble. Break out of that crap.

There's a whole world out there.

Reading your comments above I believe this is your 1st serious relationship.. for both of you. So its going to be a big deal. Take things slowly, you both seem to be going very fast. I understand that you both have had bad things happen in your past. Like I say you are both young, and there's no shame in admitting that maybe it's a first time experience for both of you being with a girl. Sit down and talk calmly with her, some girls do tend to twist the truth when it comes to previous sexual partners. Its not meant in malice. Tell her you respect her for being honest with you in the end, there are lots of reasons people lie remember.. it starts with you being open and honest with her, don't rush things & be patient. Trust takes time to build, the rest will follow
