A little bit of background information:
Me: I dated a girl for 2 years while in college, but we broke up nearly 3 years ago now. I've had a couple of "flings" since then, but no serious relationships necessarily, just casually dating various girls here and there. I'm more of a shy/quiet guy until I feel comfortable with the people I'm around.
Her: She was in a relationship previously with a guy who didn't treat her very well, and when we first met last year this was something that clearly held her back. She typically dates "the bad boy type," but is tired of being hurt/disappointed by them. She is also the shy/quiet type.
Like I said, when we first met last year, she had recently gotten out of a bad relationship with a guy didn't treat her right. We went out, but things just didn't click. We texted back and forth for a little while, but I caught her hint that she wasn't ready and left her alone rather than push the subject. Fast-forward 9 months or so, and she randomly texts me and ask how I am doing, and if we can possibly hang out sometime. We go out on a couple of dates, and things are definitely different than last time. She even invited me over to her families Memorial Day party to meet and hangout with her family, which went great.
We typically hang out a couple of times a week, 3 or so, and either go to the movies/watch a movie at home, or go out and do something. We normally share a couple of long kisses before either of us have to leave for the night, with the occasional kiss here and there throughout our time together. This has been going on for 3 weeks to a month, and we are surely getting more comfortable around each other.
Considering both of us are more of the shy type, I find it difficult to move things along without feeling too pushy. It's not like I feel she is going to reject me or anything, I just don't want to disrespect her in any way considering her last boyfriend didn't treat her right, but I also don't want to not do anything and give her the impression I'm not interested in her, because I definitely am.
Now onto my question, how should I go about making this girl my girlfriend? This is where I always fall short in past relationships, I wait, and wait, and wait, till it's too late then it's a chase to make it up. I REALLY don't want to do that this time. Do I resort to the method used in 7th grade and ask her "Do you want to be my girlfriend?", or what do I do/say? I know this sounds silly, but I always seem to stutter at this step, but I hope not to this time.
Any advice or suggestions are greatly appreciated. Thanks!
