I've used PUA techniques and using them I've reached a moderate amount of success meeting women and taking things to a physical level, but often after that it never seems lead anywhere because I have (and have developed) a high personality standard in the women I look for.

However I recently met a woman I am actually interested in pursuing a relationship with, but I'm afraid I might be giving off wuss signals and I need someone to put me on the right track, or tell me to move on.

More or less we've been dating each other almost 2 months, with about 10 dates to that time span (and yes we've had sex etc for those who are wondering). I saw her about a week ago and everything seemed fine. But lately she's been getting flaky. She still messages me quite a bit, but has been flaking on actually hanging out.

I asked her to do something on Monday, which she agreed to, but then forgot she had plans with a friend and canceled and asked to reschedule. I then said well Tuesday and Wednesday work for me, and the response was "Well I need to study and Wednesday is no good for me, my schedule the next couple weeks sucks." and just won't commit to hang out any specific time with me. I had also previously invited her to a party I am throwing next weekend, but with no response yet as to if shes coming, and I haven't pushed the issue either.

So I have several questions:

1) Do you think this girl is trying to blow me off? I can't tell if she is or not, and if she could be, what could be triggering this? She is getting a Phd so I understand if shes busy, but she never seemed THIS busy before.

2) If she is, how can I keep holding her interest? Or should I just move on?

2) Assuming she isn't, how do you go about perusing a relationship with a girl you've successfully attracted without coming off as clingy?

Any advice would be great. Thanks.

3. She isn't what?.... If you don't want to be clingy, give her space as stated

Thanks for that. She's not near many exams, but she has an active social life add that into the grad school and she can easily be busy, but its hard to get a gauge with her. She's always made time in the past... but I digress.

I think maybe an appropriate course of action is to not text / ignore hers for a few days to pique her interest and then maybe see if she's gonna come to my party, or wants to do something next week.
Assuming she isn't trying to blow me off or is still attracted, how do I go from this being a casual thing to us actually being an exclusive item?

Its awkward for me, I've only ever had girls ask to be my boyfriend, but never had to ask them to be my girlfriend. But after almost two months of this, I get the feeling I'm expected to make some sort of move in this direction and I just don't know how to go about asking it, or if its appropriate in this situation.

A friend of mine suggested that she might be reluctant to hang out because I haven't made a move yet in that direction. Not sure how much credence that holds but it wouldn't surprise me either.
