Ok guys, this is my first post i've been a longtime lurker and just wanted to start by thanking everyone who is a part of this community. I would never have gotten myself into this situation without your contributions, so thank you.

I'm going to try to keep it short and sweet. Any advice you may have will be appreciated, also just getting this off my chest will help.

I got a new neighbor maybe 3 weeks ago, I went over to her housewarming party and we fucked. During her last minute resistance she told me she didn't want to because we were neighbors and she didn't want to fuck it up. I have always wanted a fwb so I responded with "how could we fuck this up?? its perfect we can hook up whenever we get horny" She loved it, so we have officially been fwb since that night.

Fast forward to last night, I walk in and there is a GIANT vase of flowers sitting on her table. Her ex had given them too her because he is trying to get back together with her. This threw me off. It wasn't until this morning that I realized it was because I felt like she was using them to make me jealous. I was off center last night and pretty sure that had alot to do with it. We fucked and I left in the middle of the night.

What is concerning me most right now is that I actually DID get jealous and agreed to help her pick up some stuff from his house (im about to tell her now that I changed my mind, I think its a bad idea). We have been fucking alot recently and I don't have anyone else on the side so I just want some advice on the best way to handle this. I don't want a relationship with this girl, she isn't right for me plus I NEED to stay focused on school to get the grades I want. However I feel myself craving her(sex is great, she lets me do whatever I want). Please keep in mind that she is my neighbor so I want to tread carefully. Do I tell her I want to slow things down, or do I just not hang out with her for a week or so? Do I sit down and evaluate which I wan't more, good grades or a fuck-neighbor?

I guess that the heart of my delemma is: what boundaries should I set to make sure she stays a plate and nothing more? Anyway thanks again I wouldn't be here without you guys.
