Been together for over 20 years, now early 40s. We have 2 kids aged 8 and 11. We've become very different people with very different interests.
Over the last couple of years things haven't been great. More arguing, but when this happens he has become increasing snappy, moody etc. If something minor annoys him I find I'm always tip toeing around him. The latest argument ended with him slamming doors, shouting and swearing and I feel at the end of my tether. I feel like it shouldn't be this hard, and actually I'm not sure I even want to fight for it. He is always saying he doesn't get enough time to himself, but I think he would always want more regardless and any effort I put in, eg. taking kids out to give him time, is just met with the comment that the time went quickly and he didn't get as much done as he'd want. I think he has become quite self-centred.
However we have largely managed to keep arguments away from the kids (i'm aware they're not stupid and probably pick up more than we think), so I think if we split it would be a massive shock to them, so not sure if I should suck it up to keep things normal for them. There's no abuse etc., and the kids would obviously still see him so it's not like I'm removing them from (at least what I perceive to be) his selfishness.
Also he earns a good salary (circa £80k) whereas I have a very part-time flexible job, so I#m worried how I would cope financially. We have decent equity in the house but live in a very expensive area and so separating would mean a significant drop in living standards. As my kids are boy and girl I would need a 3 bed house and as eldest is due to start high school I would want to stay in the same area. I could obviously get a full time job but don't really have any experience, skills etc so would be starting on a low salary. Also I have very little in the way of pensions. My kids would see a significant drop in "nice" things that they have become used to- eg. holidays, days out etc, on top of coming to terms with the change to their family. Am I being selfish for considering this?
