I don't fancy him, never really have. I mean, I do like sleeping with him and he is a good looking bloke but I don't get all worked up when I'm around him.
He's a brilliant dad to our three kids and my best friend.. but recently I find myself irritated by him, I pick arguments just so I can ask him to move out.. and I'm supposed to be marrying him in a years time but I'm scared that I'm making the biggest mistake of my life.

Can someone please help?
I want to know whether its normal to feel this way?

Lets see, he's good looking, good in bed, a good father, and your best friend--and you're trying to drive him away.

I don't know if such behavior is "normal", but browse around the marriage, divorce, and relationship forums here and you'll see that it certainly isn't uncommon for people to prefer drama and chaos to a stable home life that's suitable for learning mature coping skills and rearing healthy well-adjusted children.

Keep going in this direction and you will lose both your children's respect and your partner's love.

How old are you and how long has this relationship been going on?? Maybe you need a change of pace, or a break to get a better perpective on things. Until this is resolved though, I wouldn't get married.

I'm twenty two, we got together when I was seventeen and had our kids... I've always wanted the kind of partner that I have, so I don't know why I'm like this, I read recently that it's a throw back to a previous relationship in your life that was filled with love but lots of emotional rollercoaster.. I'm wondering if this is the same thing?
My first "loves" were quite energetic, constantly on emotional highs and lows, its something I just don't have now, I know he will be around no matter what but I don't want to hurt him and need to make up my mind soon...
