is he thinkin about breakin up with me?

Hi Sarah, as a guy who's been through a number of relationships :-)) sometimes we need space to re-evaluate things. I can't promise you that will mean you will continue, no one could promise such a thing... the thing I believe, is to find yourself, your inner strength. It can seem a tough call at first but like anything rewarding, perserverance pays off.
Remember, when you do talk to listen to each other, respect the other person's time for talking... this is a hard one, unless you already practice this.
All I can say is the best of luck to you, and do your best to stay free of worry. You'd be surprised how we can attract the worst fears to ourselves by focusing upon them...
Go well

I think yous just need some time.
He is upset, but just give him a week or so, and yous should be okay. =]
