Sounds like you are not having much fun at all right now! How far along are they with the bathroom thing? Is there an end in sight for that project? Seems to me that home construction/remodeling is an awful thing when you have to live there at the same time. Shame none of us are like the Mittster--we can't just pack up and go to one of our OTHER houses to escape the mess and inconvenience...
The car stuff gets my total sympathy. I freaking hate auto repair issues and I make no bones about it. It always feels to me like an exercise in futility with older cars because just as soon as you get one thing fixed something else goes to hell. I have a Dodge right now that I love to hate on. I'll be driving it for the next 100 years probably, but I still hate that f***ing car and how unreliable it has been. Don't get me wrong--I kinda like the body style, but I'll NEVER buy another Dodge product again. If I hadn't put an extended warranty on that car when we bought it, literally, I'd have had to sell it due to the huge repairs bills that it has incurred. The damn thing is a ticking time bomb and I KNOW it.
Have you guys talked about a different used car or even getting a signature loan to bring everything up to snuff on your current car? It sounds like you have a pretty high amount of miles on it, but it might get you through the next couple of years if you can find a mechanic that knows his stuff. Alternately, I have been in the position that we needed a second car and could not afford much. I got lucky and bought a beater Ford Escort that I planned to drive for about 18 months but ended up keeping for several years. It looked bad, but I did love that car, and it did run pretty well with minimal outlay for repairs. If you know a mechanic or an auto sales person you might be able to find a pretty good deal on a mechanically sound car that maybe looks a little less polished but runs good.
Congrats on the wedding! Hope you can relax and enjoy the festivities. Usually the Groom's family gets to kinda sit back while the Bride and her people get all the headaches. Do you have to travel very far for the wedding?
Finally, about the husband... From what I'm getting from your comments you guys have some long running issues. It sounds like you are just maxed out at this point. I don't expect you to answer any of this, but you may want to ask yourself a few questions. Are you convinced it will continue to be this way? Do you have any hope that he can or even would change the stuff that bothers you if you guys sit down and talk about it? Do you want to expend the effort to try and fix the issues?
Ask yourself, "What if...?" What IF he walked in today and said he wants to improve? What would you tell him? What IF you won the lottery and could do anything you wanted--Would all the issues remain as pressing for you at that point? Would he play a role in your life if you were not worried about money or security? What IF suddenly he was just gone from your life? Would it be a feeling of relief or would you really miss him and feel bummed he wasn't around?
I know it sounds like I'm asking you to dig deep emotionally, but I think maybe, right now a lot of people are looking at what they have always known and they are starting to question stuff they always thought, accepted, or took for granted. Is it your feeling that maybe that is what is at work for you?
I wish you peace, and I wish you joy.
