I'd like to second braveheart's comment.

We get no where on these topics and she gets defensive discussing them so I've stopped caring about it...

I have grave concerns that the problems are being swept under the rug because either one or both of you can't deal with them. You can skip it if you want and just pretend things are OK, but sooner or later, it's going to come up again unless it's dealt with. If one or both of you can't do that, then there are issues to be addressed before you have any chance at long-term happiness. While I am happy you are back together, kind of, I fear your prospects in five years (or less).

Given the above, getting involved in any substantial financial investment together at this time is unwise.

This is a good thing to do, but if you can't successfully talk about the issues (see above), how do you expect to have any success at this? Sorry, but I'm just not seeing it.

What's happening on the counseling front? If nothing, you need to take a step back and reassess exactly what you have (and what you don't).

That having been said, at least you have some contact and some opportunities...which is more than many of us have. I hope you can find a way to use them to your collective advantage.
