Long story short. I am 26. DF is 21. I have a 9 year old DS. I bought this house in 2008, and it is just me on the mortgage (was with DS dad at the time, but bought it solely by myself). This is my home, and DS's home. I will never ever get a joint mortgage with DF, and will not tangle any finances with him.
I don't want to follow in my mothers footsteps. She has been divorced twice, and both times lost a lot of money due to property - she lost the family home when she divorced my dad when I was 9 years old!
As a result I feel the need to be independent of any man. I am the main wage earner, and he doesn't earn enough to contribute towards household expenditure - he pays for his own things, I pay for my home, and me/DS. I like it this way - it means I am in control for my future, my DS's future, and any children I may have down the line. If we have children, I don't see much changing, other than him contributing towards childcare costs, and the costs for the child/ren.
The upshot for DF is that he will never own his own home while we are together, and should anything happen between us, he will find himself starting from zero so to speak.
I worry because I don't want to do this to him, I want him to have financial security, but I am making this impossible for him really. I won't compromise my childs home by allowing anyone a chance to take it away from him/us.
Am I being unreasonable? Probably - but its out of fear...
