<human>: Condense the text into a few key points

So I [M/21/senior] have worked with a girl at my college [F/21/junior] for 2 years now. We are both in the same program. I've been in a long term relationship until this year, and now she recently got out of a few month long relationship. We have gotten coffee and lunch together, but only as coworkers splitting the bill etc.  
Anyways, she texted me to meet up at a bar last weekend. Ended up back at her place after awhile, both kind of tipsy, made out, etc. I tried to advance things and she politely told me to slow things down. 
She is going to be leaving for 3 months, 2 weeks from now. In my inebriated state I decided it was a good idea talk to about us possibly dating and confess my feelings for her. She obviously responded saying how its poor timing, she likes hanging out with me and I'm a good guy but yeah, timing. Ended up making out some more and she let me stay over in her bed since it was 4am at that point (nothing else happened). When we woke up, neither of us talked about what had happened, but me being the dummy that I am thought it was a good idea to kiss her as I left. 
I texted her the next day saying we should talk about what happened and she said she was pretty drunk but being honest about the timing and her current situation. I stated that I was drunk and tired and was probably too forward about it but wasn't sure how to approach it given the situation.  She essentially agreed and we haven't texted since...this was a week ago. We both ended up working at the same time this week and pretended as if nothing had happened. 

Should I just let it go and leave her alone? I really want to text her and she if she wants to get lunch or even just study together since it is final exams. Would this come off as needy/desperate? Am I better off waiting until she gets back and let my fuck up blow over?
<bot>: Got drunk and made out with coworker. Confessed feelings, was awkward as fawk. Want to follow up without seeming needy, but she leaves for study abroad in 2 weeks. what do?
