As stated above we are new in this relationship and often while we are making out i try to go to the next step and she says "I need more time"(been a few weeks and she says she needs a few more).

This makes me get frustrated and a little angry(its noticeable), I dont know how to handle it.

Should I act like i dont even care, or put my foot down and be like i 'either we do what i want or we are not even kissing anymore'.

Edit: thanks for all the replies guys, but apart from breaking up with her how should I react to this situation?
