Hi there,
No I'm not a counselor, but I do have recognised qualifications in helping people manage difficult circumstances - how they got into them, and how best to get out of them, plus a careers' worth of time in working in the dynamics of various abusing situations. In that, I now manage/lead and train staff in doing that.
I'd think you're right re avoidance. What energy and time he has expended over the last year or so is v probably just going round and round with the same thoughts/feelings, producing lots of heat but not much light. One real problem is that many people simply don't have the 'vocabulary' to convert those thoughts/feelings into something meaningful – they remain as a confusing mass in their heads. That's where talking with family and friends help out, usually. In that, you ask 'what is going on with my dh?' He probably doesn't know himself. You've only said that he isn't sure he feels the same. So what does he feel, if not 'the same',and why? Has he said anything about the why?
The patience thing – you know its been barely a week, though it will prob. feel much longer. Whatever happens in the long term, you will need to satisfy yourself that you did all you could, that no rash decisions were made, nothing unreasonable was demanded, no 'trial' put before him that you knew he couldn't meet. The last thing you will want is a circumstance where you are at all regretful for acting in haste to your and your dc's detriment. Patience will be your safeguard.
Having said all of that, you have your needs! And he should be meeting them with some action. It's not unlike living with a chronic drinker – look at what he actually does, rather than what he says he will do, and accept no excuses. The timing was pretty poor, but at least he got round to opening his mouth, and he needs to keep it open, via counselling (in the lack of other outlets other than you.) Feelings like he described don't just 'go away' – they get subsumed into some other behaviours. IF you do go to couple's counselling, expect some surprises and hearing things you don't really don't want to hear. I've not been to this, but lots of anecdotes show this.
Oh and thanks for coming back! In DN we get a few questions like these, which are one post and then we never hear from them again.
