I'd say that we have a pretty healthy relationship.
Full, equal access to funds (regardless of whether I'm working or a SAHM). Discussion of all unusual purchases.
Childcare and housework split equally if I'm working. If I'm a SAHM I do the bulk but he'll still load the dishwasher/do the occasional load of ironing/put the bins out/make the odd meal etc as needed.
Both have equal opportunity to pursue hobbies.
Sex - we can both say "no" without recriminations.
We discuss problems/worries/irritations as soon as they come up to avoid resentment building. Occasionally we argue but not often and not for long. The possibility of an argument wouldn't put either of us off raising something.
We are each other's best friends. The person each of us turns to first with a problem, for comfort, to celebrate achievements or for help.
I'm sorry that you've had such a hard time.
My advice for the future would be look for a friend. Don't put up from a partner behaviour you wouldn't put up with from your best friend.
The marriage vows are well written "for richer for poorer, for better for worse, in sickness and in health".
Look for someone who adores you while holding your hair back as you throw up, someone who'll hold your hand as you cry and support you if your world falls apart.
Love isn't in grand declarations or gestures, it's in the everyday nitty gritty, the everyday grind.
Look for someone responsible, conscientious, trustworthy, kind and fun.
Look for someone who you can talk to all day long and who makes you laugh.
I hope you find someone wonderful.
