This girl is in an LTR but we get along very well and flirt all the time. She frequently messages me. I'm sure her relationship is probably dead and the only reason she's with him is because she doesn't want to be alone (they would rather branch swing than fall off the tree), which is very frequent, I think she doesn't like the guy. Anyways my question is how do I escalate? I'm kinda scared to go in for the kiss or touch her because she has a boyfriend it's more likely she'll reject me. If a girl was being so flirty with me I would go in without a second thought, but I never dealt with women in LTRs. I wanna plate her, and she seems down, how do I go about it?
