Basically Im relatively new to the PUA scene, but over the last few days I met a girl, she's very nice, not a stunner, but not the best looking girl, but I like her. Anyhow, we met at a party and afterwards were both tipsy, going on sober. I ended up walking her home. She wasn't my aim for the night, rather someone else was, but in the end I cba due to how ill I felt. So I end up walking this girl home and just casually acting as myself, but she's trying to hold my hand which I oblige to. I throw a few negs and tease her a bit and eventually we kiss.

We text and flirt, during the day we decide to meet. We go for lunch turns out to be ok in my view, casual chat. Noticeable thing we're acting like a couple already (but only just met within a matter of hours previously). We then head back to hers (again with the hands) and eventually make our way to her room where the inevitable occured.

Now that was a few days ago, in between casual texts have been sent between us. But she's going home from Uni for the summer and I don't have a clue when we're gonna see each other??

The thing is I've text her a few times and phoned her once with no reply. I'm stopping it at that and leaving it until I get a reply as I don't want to be the annoying git. So far things seem ok. I don't want to be seem the needy dude, but like I'd love to see her before she goes as I don't know when we'll be next seeing each other. Obviously we just met and shagged, but I dont want to screw this up. Any advice on signs, what to do or anything is much appreciated!

Well it sounds like something happened between the time that you hooked up, and where we are now. You may have dropped the ball with the casual texts afterwards, you may have creeped her out (saying you'd "love to see her" to us may have been conveyed to her in through these messages, again, I don't now though)
Most likely it wasn't your fault. She may not want to go further and be attached (since she is leaving and you guys obviously will not stay in touch for a while). She may be very busy with wrapping up the year, and believe it or not you're not number one on her mind. It's not always your fault that they don't respond, so don't beat yourself up too much. Just analyze what you sent and what you did, and clean anything up for next time.

Right lads I need your help fast

As contrary to the above something was going on that caught me out of surprise. Turns out this girl I liked wasn't avoiding me for a reason, turned out she liked me quite a bit and really wanted to meet me. However she bumped into the ex and it screwed her over, confused her etc.

Now we had a chat and I got the whole how I need to clear my head and see how I am, i really like you, but kind of like him, but dont want to get back with him and its getting me down etc etc

We know this is a classic scenario where LJBF can become a major factor here, something I intend to avoid, question is how?!?! I said yeah you need your space and I'll give that. What do I do? Mention I like her and she should be with me, carry on seeing me or what? I like her and need to avoid the LJBF, so any advice at all is much appreciated!
