I think it would have to depend on the problems.

I personally have trust and self worth issues so it takes a lot of work to get me to trust you but then I don't feel I'm worth all that effort so I start thinking the other person must be up to something malicious.

It's hard enough to have your love questioned constantly without the added lashing out and pushing away I tend to throw into the mix.

I can't subject another person to that. They don't deserve to suffer because I don't like myself.

And that's where I believe the line is drawn. Relationships are hard but when one person is causing another to truly suffer because of their issues then I think that person needs to be working on themselves before stepping into a relationship.
