TLDR: Things were going great, she gets a temporary bar job that made it hard to meet up for 3 weeks but that ends soon. How do I get the momentum going again without seeming needy? Btw, I know there's a good chance she's lost interest but it would be silly not to try and I'm seeing other girls already.
Context:
- I'm 30, she's 22.
- Met 5 times over a month when she had no job. Every time we had sex (experimented a lot, she seemed to really enjoy it and I got her to try new things), she would stay over, shower together, had breakfast together. Last time went great as usual and we had a few decent messages back and forth after.
- She gets a bar job for a month working 10 hour shifts most days which started just before our last meet up.
- I ask her out for the next day at one point and she says she's meeting friends. She doesn't usually give an alternative day and didn't do it here either.
- The amount of interest she showed on txt seemed to change suddenly which I took as a very bad sign. I waited a week, asked again. I made a statement and ask to meet for a drink, she replied quick with a question about the statement like she was changing the subject, I answered, asked if she is going to meet me and she said she was probably working all week. The way it seemed like she was ignoring the question seemed very bad...
- I waited about 2 weeks when I know she's nearly done with her job, txted her a teasing message (I didn't want to look like I was sulking by ignoring her too long) and she replies within a few hours along the lines of "hahaha something like that, I've been partying all the time too

" (seems a positive enough reaction to me, if she wanted to ignore me she could have been much more blunt)
- I'm pretty sure she's done with her job now so she'll have lots of spare time.
- I've no idea if she just wants fun or something serious. She's young so probably not.
- What do I do next? Assuming she's still interested, I don't want her to take me for granted and going from messaging and meeting often to this is jarring.
I reckon she got caught up in the partying life most people that I know work in pubs get into, maybe she met someone new at work, who knows, doesn't matter. I'm hoping she's going to get bored soon as that will be finished now and she'll have to go job hunting.
My plan was to wait a few more days, try and get a conversation going with some funny+flirty stuff, let her know how busy and interesting my life has been, maybe wait a bit more so she doesn't expect me to ask her out every time, then ask her out for drinks when she's responding well. My main concern is not to come across as needy and looking for tips to rekindle things after we've been out of contact for a while.
