He's been out of work for 9 months, and that's a third of the time you've been together. So you've been together not much more than 2 years, and you always have a wedding planned and a date everyone knows about. So you were engaged before you'd even known him 2 years.
Now, 2 years isn't 5 minutes. I got engaged second time round after 3 months
but we're waiting another 2.5 years to marry. So I'm in no position to say you're rushing it, and I don't think it is really rushing. But you know... less than 2 years of knowing him, to commit to marriage. It's OK to have doubts.
I'm actually impressed that he started his own gym. I think it might show a certain drive and that's exciting and would attract me. The fact he didn't make much money from it wouldn't concern me too much. But...
You say it was jointly owned. Did he actually have the drive or was it actually the other person who did all the work and he just worked there, and was only a partner because his parents put up the cash because they just want him to stick st something?
You say he had to leave... why? You don't have to answer that! But it would influence me as to whether I saw him positively from the gym time or not. When he left the gym, you'd been together 18 months and would have been in new boyfriend bubble. Did he get fed up with the long hours, start not pulling his weight and get pushed out?
Because then I'd think about his character and what that means for being a SAHD. I don't want the SAHP in my relationship to be chosen simply for financial reasons. Does he actually WANT to be at home with children? And if he seems to, is he the kind of man who has only short bursts of interest?
Compare it to the gym... is he going to throw himself into it for a year (or not at all?) and then just sit around playing Xbox when you had imagined him taking 3 kids to the park every day?
I find it hard to believe that he can't find work, to be honest. Easy to believe that he can't find the full time perfect job. But as he's not under pressure for that, he has the luxury of not needing full time. He hasn't had the drive to take on personal clients. My gym (small city in Midlands, not an employment hotspot!) is always advertising for front of house staff, albeit part time.
It's not about does he work, but does he have drive. I don't care about low earning and choosing what he loves over cash.
But in that case, what he'd have to love is being a SAHD.
Do you really think he would?
Forget the convenience of it.
You know that if he's not interested in something, he doesn't do it. Getting up in the night, nappy changing, endless fucking singing of the wheels on the bus, yet another Peppa Pig conversation, toddler tantrums... lots of full time parenting really isn't that much fun.
If he applied to be your male nanny, with his CV and what you know of him - would you recruit him? Honestly?
I think you need more time to see the patterns in his working behaviour. You met him during a positive own-his-own-business phase. Is it possible that after 10 years together you'd now see a pattern of never sticking to anything for more than 18 months?
I think you should wait more time to get to know him better, and never choose a SAHP because they're convenient - choose them because they are right for the "job".
Running a bath ain't all that!
