<human>: Can you summarize the given text in a few sentences?

This is my first relationship, and it's been insanely stressful for me (it's been going on for almost 2 months). My girlfriend has had a few relationships before, but all of hers have ended because she stopped liking the guy she was dating and left him after a month and a half. She told me this happened at the beginning of our relationship but said "ours felt different" then when I brought it up a month later she said the same thing. Regardless, I've still been paranoid and I have no idea how to stop feeling that way.

Recently, there have been a few more issues. We talked about our relationship a bit more and she told me that so far us dating feels like we're just good friends+the physical stuff; there's no giddiness feeling that she needs for this to feel like a successful relationship (and she doesn't know how to get it either). We decided we'd see if it develops over time but recently she's been pretty aloof and I'm worried she's not putting in the effort to keep this alive.
<bot>: I can't stop feeling paranoid, and my girlfriend needs to develop that feeling she calls giddiness (seems like another word for it is love), but neither of us know how.
