<human>: We've been together about 4 years and she means a lot to me. I recently moved away and due to her work and mine we won't be able to see each other very much this year and perhaps next year.

 I've been missing her a lot,  really struggling but now it's looking to be over a 3 Month gap as a visit at the 2 month is at a really bad time for me.  The thing is now I don't think I want her to visit anyway and the thought of going home and seeing her after that long scares me.  

I feel after that long things will be awkward,  I get like that after shorter periods of not seeing each other but I think 3 months and we'll be too different.  She seems to be fine after these gaps but I can never shake the feeling that things aren't the same,  she isn't the same person I saw last time and it takes me a while to warm up. 

The longest previously is about 5 weeks,  I went I think 3 days feeling weird, this feeling always stops after we get initimate sexually but I can't usually initiate it. In this previous gap I tried to avoid seeing her and she had to see me but didn't know I was avoiding her. 

I would speak to her about it but it needs to be done in person and I'm already in avoiding mode, plus she has a lot going on and I don't want to add to that. What's going on,  does anyone else get this?

Can you condense the text into three sentences or less?
<bot>: Long breaks make me avoid gf and feel awkward with her. Sex seems to fix this. What's wrong with me?
