<human>: To give a little background here.

I suffer from Asperger's syndrome with social anxiety & inner moodiness, thus while I can give good first impressions, I get frozen when going further than that.

I started at a new job several months ago and started to know a woman that I became quite infatuated at. We became at first quite social to each other, greeting and sitting near at the table when eating. She's really extroverted and outgoing, compared to me. 

However since she's in a committed relationship I wanted to respect that and keep my distance. I started to be less upfront but maintained being civil when greeting. However gradually her responses became more distant and whenever I try to make a conversation (not easy, making up topics), it either goes fast and/or with a negative answer. She still greets but I feel through her body language  that it's made as just a routine, only having to do it once so that she's done for the rest of the day. Also during lunch she sits beside but I feel the vibe that she does so so that her eyesight is not directed at me.

I also feel anxiety for the fact that another co-worker (M, married) have started to hang out with her and have great chemistry, possibly due to his good humor.

My question is how I should handle this, knowing that I'll be soon quitting my job (temporary employment). While the usual response would be to move on and ignore her for the rest of the work, a part of me wants to get loose, and having the risk (during a bad mood), tell her when she's greeting that she doesn't have to if not wanting to. Our positions are not related nor depended on each other so we rarely meet for the same assignment.

This feel over dramatic but I've been having a lot of trial-and-errors when it comes to women and want to improve for my sake.

Give me a shortened version of the text
<bot>: Want to be respectful to female coworker that I've became infatuated with by becoming more neutral. Feel like she responds more resentful.
