Anyone who's been tired of their marriage

ive been married for 6 years and we have 2 kids together. my husband was wonderful.....at first. but he has become an uptight, grumpy person. we fight over the dumbest things. hes very insensitive and so negative. for a long time i was saddened by the way i feel and didnt think i would ever want to leave him. well, our kids and i went to visit him (were both military and hes in training right now 2 hours away) a few weekends ago and he did/said some very upsetting, insensitive things to me. it really hurt my feelings to the point where we left to come back home first thing the next morning. i didnt call him (im usually the one that calls and talks about these things) at all until a couple of nights ago. there was no mention about what happened the first time we talk. the second time we very briefly talked and reconciled. ever since then ive been thinking about it...and i dont really want to be with him anymore. im not sad or upset, i just dont want to be married to him anymore. i guess ive really just had enough of everything. since hes been gone theres no bickering and things are more peaceful. just the way i like it. i love my husband and i always will. wouldnt have married him if i didnt. but im not in anyway IN love with him anymore. has anyone else felt this way? what did you do about it?
