There is no time limit for the butterflies. Just for as long as you're loved up I suppose - LOL
The butterflies is a good sign as if he makes you feel this good it's a good sign.
Don't put a time limit on things as all situations vary and you will just frustrate yourself once this time has elapsed and the situation hasn't changed.
It's all fun, so just go with the flow.
I'm a very impatient person and i start to get insecure if a man doesn't call me or text me all the time and it's daft of me really.
This other guy is still making his mind up, but don't put you life on hold for hom.
See the new guy, see how it goes and if the 5 monther does move near you, see how your life is at the time.
You could be loved up with new guy or u could hate him.
Only time will tell and i don't think you can really make a decision until the time comes. It's hard to determine what could and might happen that far ahead and how u might feel.
Just don't sit around and base your life on other PPL's decisions, do what YOU want and as i said before, it'll all work out
