Not sure what to do

[JustAGuy]

So I'm happy when I'm with my girlfriend like chilling or seeing her but sometime I don't see her for a week or two and then I seem to lose interest, or not be as happy. Is this normal and does it happen to you?

Maybe it's just you forgetting how happy you are around her because of being away that long. Find ways to see her for consistent amounts of time and this may change.

Maybe you just need to spend more time together. I don't think it's normal that you lose interest.

Hmm it's either A. you need to spend more time with her, or B. is a sign saying you two are not meant to be with each other! To be in a relationship you have to mentally like the other person non stop, or it's not a healthy relationship! So she may like you all the time, but if you loose interest, it's not that healthy when one does, and one doesn't!

Well since you're happy whenever you hang out with her it's not a loss of interest, it's you being comfortable.
When you're with her, you're happy. The emotions, hormones, all that happy yay my girlfriend's here! stuff.
When you're not with her, you're sort of in a clam state of stasis.
