<human>: Can you succinctly summarize the text in 1-3 sentences?

I met her several months ago and we're dating. At that time she claimed to have fear of commitment and I was enjoying the state of being unbound after a recent breakup, so we agreed on not having an actual relationship, just seeing each other whenever it's convenient.

This seemed like a really good solution. I also made clear to her that I currently place high value on spending most of my free time by myself. She said she was totally ok with that. However, she quickly started to become very clingy.

She calls me every evening and she obviously expects to see each other every weekend. When I told her that I want to spend it by myself, she was very disappointed. 

Just recently she asked me if I would like to spend a weekend with her and some friends at the end of September. When I said I have no idea whether I would feel like it, she wanted me to make a promise. I then explained to her that this contradicts our agreement and I start to feel like she's crushing me.

She was a bit insightful after that but also disappointed and kinda sad. She definitely developed serious feelings towards me, but I don't have strong feelings towards her. 

I have bipolar disorder and I explained to her that I will probably have times where I would act strange, being aloof and not in the mood for anything. She said she would be ok with that, but then again, she kept asking me what's wrong and was disappointed when I wouldn't have sex with her. And if I do, in order to not hurt her feelings, it just crushes me, because sex can be so exhausting and disgusting if you're emotionally not involved at all.

I think I need to tell her that she needs to slow down with her affection because I feel trapped. But then again, I don't want to hurt her, and I am also too much of a good liar, so maybe she really thinks I have strong feelings towards her as well.

What should I do?
<bot>: I currently enjoy being by myself and she requires a lot more than we agreed on. Need to make it clear to her that I need some space (don't want to lose her though) without hurting her feelings
