I didn't know your man was backing out of a relationship, Aeradalia. I'm sorry to hear that.
A relationship (especially a young one) should not be really difficult to maintain. I believe you are moving towards the female version of the "White Knight Syndrome". Be careful helping a man out. Once he "gets better" he may dump you for a woman who wouldn't do such a thing for a man.
Men really don't want a helper for a spouse no matter what they say to you.
Here's a test: Don't do anything for him and watch how he suddenly finds you more attractive. Helpers are nice but they do absolutely nothing in maintain or building up attraction.
Let him get the counseling, financial advisor, or whatever his issue is all on his own. Give support and show care, yes, but not do these "maintenance" stuff as Giga has put it (which is my definition of high maintenance too) just to keep him and the relationship going smoothly.
I agree that he sounds high maintenance.
Just saying.
