Wow. Sounds like that got WAY out of control. Listen, clearly you guys need to have an open, honest conversation with each other and sort out all of this anger, confusion and resentment. You shouldn't hold his comments during the fight against him just like he shouldn't hold yours against you. Doesn't matter that he said it first, you said it too. Were you being serious? Then why are you assuming that he was?
It feels like there might be more going on here than we know (and after reading your previous post, I'm certain there is). Do you have other reasons to fear he's being unfaithful? How long have the two of you been married? I know my hubby and I have had some NASTY fights and said some pretty wretched things to each other, but they've always stopped short of someone getting kicked out....let alone for days.
Look, no matter what your situation, nothing is going to get resolved unless you guys are communicating. Find a way to have a calm, mature discussion with this man about your feelings and the state of your marriage or things will only get worse.
Once this has settled, I HIGHLY recommend you guys get some marriage counseling. Or even find a local church (if you're not already attending) that offers good, Bible-based marraige enrichment classes. I'm sure many are available for free online as well.
In the meantime, hang in there. And if you're a believer, pray hard for husband and your marraige. And then...cast your burdens on Christ, because He doesn't want you to go through this alone.
Much love,
