What will long distance do to us?

Hi,

My boyfriend is Pisces.

Over the last months, we had a lot of fights and arguments to the point he almost broke up with me but decided to give us a second chance. He says he's broken and sad. We live together but he refuses to kiss me and barely hugs me. I feel awful. He says a loves me to death and that his feelings are sincere. He knows I'm crazy about him too.

I'm going abroad to work for 4 months and I'm scared he realises he feels better without me.

Do Pisces move on quickly? Will he kiss me before I go? Will he realise he prefers to be without me?

I'm in limbo.

Thanks for your help.
