I agree partially. No, not all you need is love. I've heard countless couples who have been together for 15+ years say that they are more in love with their spouses now than when they first got married. I've been to many marriage seminars, read many books, basically I do whatever I can to make my marriage more appealing for myself AND my wife. It's a 2-way street. Yes you need love, but you also need to be able to know that no matter what happens, whether it's in your control or not, that you will be together. Once you get married and say those two words, you become one and you agree to work through the hard times. "Through richer and poorer". From your original post, I don't see her being able to say "yes" to that honestly but of course, you aren't yet married. Perhaps that will change by the time you do decide to get married. If not, I'm so sorry for you and wish you the best. Anyways, married life isn't about surviving, it's about taking the life journey with each other. Remember, you become one, so if she, like you said, ends up in a wheelchair, gets cancer, goes brain dead, you name it, you will always be there for her. She needs that same mentality. You owe it to yourself. Take care man!
Once again, good luck on the new job! Hope it fulfills your financial needs!
