<human>: Not much of a story. My ex and I are not together anymore, we both have come to the conclusion we want to see other people/explore/be independent (her more than me but I still agree).

We had a long relationship, and I still am in her life, we text occasionally.  But we basically share a dog, which lives with her. So she's going away this Saturday, and since I know the family well and they trust me, they asked me to house sit (which is awesome)

So I've been spending some time over their house lately, my ex hasn't left yet, but she's been busy with school and friends so she'll come home every now and then. 

I want to know if I should make a move. I don't know if she's giving me signals or just being kind/pitying me.

To get to the point, I've been around her changing, last night she was trying on dresses for a party and asked me to give my opinions, letting me watch her change. She took a shower and we talked with me in full view of her. Then we were talking in bed (her bed) about her current escapades and while we weren't touching or anything, her feet kept pressing up to mine and I feel like there was definitely some sexual tension. 

I don't want her back right now or anything, but we had a great sex life, she always talks about how we had the best sex etc etc. I'm torn between being spontaneous and making a move and being risky, or hurting her feelings/breaching her trust. What do you guys/gals think?

Summarize the given text in a few sentences.
<bot>: Don't know whether signals from ex are kindness or actual signals. Don't know if I should take charge and just go for it.
