<human>: My boyfriend, in the beginning of our relationship had mentioned that, after seven years, he'd found a girlfriend that he could be in love with again. With that I'd asked, "What do you mean?" Because he'd mentioned that he'd been in love with this girl that had left him (without even saying anything) - basically his 'one that got away'. Anyway, I hadn't mind being in a relationship with him since I like him and the sex is great.

But now, since he's been being all lovey dovey, I feel like a jerk because I guess I don't feel the same way since I'd gotten into that mental state where, "I am the replacement" after having "the one that got away".

I feel like a jerk because I know I'm just here to pass the time. But in terms of fully committing, I think he's not the one.

Is there something wrong with me?

Could you distill the essence of the text into 1-3 sentences?
<bot>: My boyfriend's a nice person but had conditioned me that I was just a replacement for this ever recurring 'the one that got away' chick and now I'm not taking his love seriously. What's wrong with me?!
