Apologies because I think this is going to be long but I could really do with some advice and haven't discussed this with anyone in the 'real' world.
Bit of background-
I'm 26 and met my husband when I was 16 (he's 6 years older). It was my first proper relationship in every way. He wasn't someone I would normally be attracted to but he made me feel safe and secure (after an unhappy childhood) and treated me right. I was only 16 so this made me feel like a grown up. We moved in together when I was 18 after my grandparents saying we had to get engaged first, which we did. Fast forward a couple of years and we had our first daughter and got married. We then had our second daughter 2.5 years later. It is now 4 years on (we've been together for 10 years and married for almost 6).
Here's where my problem is - I don't love him in the way I should. I'm not sure if I've ever loved him properly as I haven't had any experience of love. I love him like I would a sibling. I've told him this but he says that it is normal for couples for feel this way sometimes and we can work through it. That was about a year ago and I still love him like a sibling.
Another thing is I am in no way attracted to him. We have sex maybe 4 times a year if that. He has put on a lot of weight and won't do anything about it whereas I've lost 7 stone and am in the best shape of my life. He eats the meals I give him (sw ones) but it's all the snacks etc on top of this. I think he has put on about 4 stone since we've been together. I've tried to encourage him but he doesn't want to know.
He has always had a temper (the red hair in him) but has calmed down a lot since we've been together. Now he gets moody over such small things that it's like I'm trying to talk to a child. The girls know when he's in a mood and I try to keep them amused until it blows over. Then he's sorry and we all have a laugh over it. I don't want to be like that anymore.
He is not a bad man and he is a great dad. I know that we wouldn't be together if we didn't have the children but now I'm thinking do I stay because of the girls or should I try and be by myself? He is the main wage earner by quite a way and my lifestyle would change quite a lot but I know he wouldn't let the girls go without so I could manage.
I want to see what else is out there in the way of life and relationships. I don't want to be like my nan or friends who look back on their life and say they wouldn't have stayed in the relationship.
I don't want to hurt him I really don't but I've had these thoughts for so long and each time I say that I don't want to be with him, he talks me round and we start the cycle again.
It would absolutely break his heart.
Sorry for being so long. There's loads I've missed out but don't want to bore you anymore! Well done if you've got this far. It's helped writing it all down.
