@MrsWooster agree.
However unpalatable it maybe for some posters to read, there is a MASSIVE difference between a person with health issues who accepts help, medication and helps themselves and someone who refuses.
The latter are tedious and tend to drag those around them down with them.
Life can be hard enough without starting out a life together already doing the heavy lifting with someone who is slow to help themselves.
If the OP ever had hope to have a family, she ought to think long and hard about who would provide financially and be the main stability in a family with one partner unable to work at times with MH problems.
Women invariably do the overwhelming majority of the caring/mental load with children, so it would be unbelievably naive not to give this some honest thought.
However unpalatable it is to some posters, the real world involves dealing with looking at worst case scenarios, being prepared while hoping for the best.
Just jumping straight in and thinking love will get us through it, is unrealistic.
Marriage, children, providing and paying for a home has never, ever been more challenging.
Thinking it will be anything but difficult with a partner who has regular periods out of work is madness.
He is very lucky to have a supportive family.
No doubt living off them with minimal rent has helped with his savings.
Will the OP be happy to be starting out sharing costs with someone who several times a year may not work?
There is nothing wrong with self preservation and being brutally honest with yourself about what your hopes and expectations are for the future.
After all, it will be the OP that will be left with it all on her shoulders if things go wrong.
She needs to be prepared for that in her choices.
