Will add just one more word of warning:
EVERYONE thinks that their situation is special, different, and whatever bad thing happened to other people won't happen to them. Everyone. And they are always shocked, shocked! when it actually does happen to them.
Since you are a union electrical worker: How many anti-union people do you know who think they will NEVER have an employer who is exploitative and provides unsafe working conditions, and they will ALWAYS be able to find another job with better working conditions if they don't like what they've got? How many anti-union people do you know who believe they will ALWAYS be able to fix, negotiate or leave a bad work environment?
Everyone thinks that THEIR precious angel kid will NEVER be a bully, a brat, or need corporal punishment. At most, they might admit that Junior "has some emotional problems but is a nice kid deep down inside, where only I can see it," even if their unsocialized little monster acts like a demon on crystal meth and has already killed three other people.
Nobody thinks that THEIR spouse/SO will ever abuse them, steal their money, leave them for their 20something secretary, or any of the other despicable things that spouses can do. Everyone thinks their case is special.
I'm not saying that your fiance is a bad guy or will ever do anything bad to you--I'm saying, don't think for one minute that somehow YOU are an exception and unlike everyone else in the world, YOU will be lucky and not have any problems. Don't think that we all get this advice by watching Oprah or something; most of us have learned this stuff the hard way, and we never thought it would happen to us either. When you accept that bad things happen and love is sometimes NOT all you need, it's a lot easier to get to work on fixing things and making them better in the long run.
His story is much different from most . He got his ex pregnant and his dad told him he had to do the right thing , so he did , for 18 yrs. He traveled alot because there was no work in the state , but he loved it because he didn't have to be around her . He makes good money , yet he was always broke because she spent it . She was a stay at home mom , who never cleaned the house (I can verify this ) . She goes out of her way to bad mouth me in front of her children (big no no ) and only calls when she needs money .
This is not a very different story. Lots of folks I went to high school with tell the same story. Lots of folks here can probably tell a similar story. This happens all the time. You do not want to assume that things will magically be different for you. This story should tell you that he is impulsive (got ex pregnant young, presumably when they did not have a stable relationship), that he is easily led (went on to marry someone he did not love or have a good relationship with, for 18 years--he could have stood up to Dad and mailed child support checks), that he does not stick up for himself much, that he is not fiscally responsible (gave all his money to the irresponsible wife while knowing she was not going to spend it responsibly), and finally that he does not have any spine to stick up for YOU unasked or make any effort to fix problems in relationships.
I'm sorry I'm being so harsh, but I would worry that after you are married, when you DO have a problem (one will happen, if you are married for any serious amount of time--illness, accidents, money issues happen to us all), he will not be there trying to work things out. That takes emotional strength and it's a lot of work, and it's a lot more than just communication. I can talk to my husband all I want about, say, the electric bills, but if he just sits there and agrees with me, then never actually turns off lights when he leaves a room, it doesn't do any good.
