is it possible to compliment my girlfriend too much?
Yes. It's like money, if you print more money but you don't make any money then it will cause inflation and money will worth nothing. Just like complimenting her a lot, she will get used to being complimented.
Yes, they will get annoying and eventually loose value.
Yes if it is taken to be as more of an obligation she will eventually find it to be annoying. If you mean it, and aren't too cheesy, it shouldn't be a problem
Too much of anything isn't good.
Well, if it was me, I would begin to disbelieve in the sincerity of a constant stream of compliments. So, yes, compliments can be overdone.
Yes, she could either get creeped, annoyed, or eventually feel like they don't mean anything.
yeah just take it down a little like 50 compliments a day should be fine = /
Yes, It's happened to me & it ruined our relationship.
