Here comes the 2x4 of The Way devotedman Sees It. Remember, take what you want/need and leave the rest. (Also, great to see you again! Hi!)
Strategies are the things that we do, the plans and behaviors that we have, to get what we want.
You say:
I think the rockiness comes from us both being so stubborn, short-tempered, and of a certain age when our habits are not easy to change. I'm 35, he's 42 this month. We are both divorcees our marriages each ending due to our partners' infidelity. Of course, like most people, we have our FOO issues as well. We argue over stupid things, just basic differences of opinion. We always seem to come back a little after an argument and talk it out.
So, you both have strategies of stubbornness, short-temperedness, and blameshifting the inability/unwillingness to change on your ages.
How well are these strategies working to get what you want?
To answer your question, I think that you both want to be together. That's an assumption. I assume also that you're feeling a bit overwhelmed by it all and so thoughts of, "Oh, just chuck the whole thing and live in a nunnery!" are normal. A bit dramatic, perhaps :vD but normal. They're normal because you don't really like that particular status quo, but you also don't know how to get out of it.
Here's what I'd do:
First, sit him down and hold his hands (this is important, it creates and supports the feeling and thought that you are being sincere) and calmly say that you don't think that your communication styles are helping your relationship. Tell him that you'd like those styles to change, so that you can communicate better and more effectively and so that you can really enjoy your time together instead of just enduring your time together.
Second, start looking for books that discuss effective communication and working on effective communication.
Third, realize that anger is often a secondary emotion, a defensive attack. Try to work out why you're feeling attacked and ask him to do the same. Is it a reaction to not wanting to be hurt by an SO after you've both had WS-es? Are you both trying to push the other away a bit as a test? Are you both somewhat afraid of trusting again and anger works against trusting again?
Fourth, recognize that you're not too old to change and that if your current strategy is not getting you what you want, well, change that strategy!
By the above (fourth), I mean that your communication style isn't letting you figure out clearly whether to stay or go. Well, change to a communication style that will, or change to a style that'll let you and your SO figure out calmly whether or not to stay together.
Don't let a moment's pride and anger destroy something that you want. And, before it does, figure out whether you want the thing or not. I think that the above that I've posted should help with that.
I wish you the best of luck, jg84.
