I am 35 years old and i have a near perfect credit score, so I am not going to be objective in my answer.
Before I turned 18 and received my first credit card, my mother instilled in me the perks of having good credit. Now, she didn't "drill", but she let me know how important it is not to go into heavy debt and play your money safe. As i got older, I read more articles about what credit scores do for you and how to keep them high and what makes them go down, etc... just so I'd have that knowledge...
I don't make tons of money. I played it right. I didn't go on extravagant vacations. I didn't buy a bunch of stuff just b/c it was trendy. I saved my money. I used credit cards correctly. Now that's not to say something terrible couldn't happen to me tomorrow and things go down hill fast and my credit score could go down the toilet. Some things are out of our control. Just because someone has bad credit doesn't mean they are poor money managers.
Now. when I was in my late teens, very early 20s... I dated a guy a few years older than me that did not have the same viewpoint on money. But neither one of us really had full time jobs at that time really so I couldn't really tell how he would have managed it. We were engaged for a short time. We had other issues and broke it off, but that was one of the issues I had with him. He was one of those that would be a "pay you later" guy but never paid you later. (even after i let him borrow hundreds of dollars from me, i eventually had to act like a bank to get it back from him). Really glad I didn't marry him for that reason and other reasons.
Shortly after that, I began dating an older guy--like 9 years older. Who already had debt. Quite a bit of debt. Didn't know before hand really how much. (it was a rebound relationship, of course, so we got seriously quickly). Anyway, I was really disheartened to learn about 8 -10 months after we started dating he was giving me more details about how bad his credit really was (before we moved in together, he wanted to let me know that maybe we shouldn't even try running him on any loans b/c it would just be awful) During this conversation I learned he didn't really know how much he owed from the past and it didn't seem like he was trying to "fix it". After we moved in together, I watched for signs for this. (course only my name was on the lease and we signed a one year lease that i could afford if worse case) He blew through his money. When he had extra money, he'd go through it pretty quickly. (we kept separate bank accts). So...after that relationship failed due to mostly other reasons, I told myself.. "do not ever get serious with a man that does not know how to handle his finances."
It does not matter what a person makes... it's about whether they know how to manage their money. I don't make tons and tons of money. But I make enough to be comfortable and save some back. I own my own house. I have a car that is paid off. I have a full time job. Do I have all the latest technology? No. I know my limits. I weigh my wants and needs. Sometimes I let loose and live a little b/c we all aren't promised tomorrow. But I can stand on my own two feet and that's basically what I look for in a potential husband too---someone that can stand on his own two feet. Knows how to handle his money--no matter what he has.
If you can't be certain about this man--whether he handles his finances well or not--then keep talking to him but do NOT get serious with him. Do not revolve your life around him. (Ie don't hang out with him ever chance you have) When you do see that he is a man that does not know how to handle his money well and it seems as though he can't stand on his own two feet, then you will have you answer.
At my age, Im not waiting around for some man to "get his stuff together". I'm passed that. I could have dealt with that in my 20s, but not now.
