<human>: So, I've known my friend for a few months now and we got along well together right off the bat. Our relationship has become really flirty towards each other recently and even though we've not known each other for a long time we can talk about anything with each other.

Here's where things get complicated. We both have long term relationships going on and are both living with out partners, which is screwing with my head. However when we are together with other people we do seem to be in our own little bubble together having our own conversation.

She also rarely mentions her boyfriend and when she goes through pictures on her phone with me of her and her family she seems to try to avoid pictures with her boyfriend in them.

I'm not sure whether or not this is harmless flirting or whether she wants something to possibly happen in the future between us, but I'm honestly starting to have feelings for her. Any opinions or advice on this situation would be great.

Can you give me the gist of the text in a nutshell?
<bot>: been back and forth flirting with a friend despite both of us having partners, wondering if she may want it to lead somewhere.
