Here is what I get out of my relationship...
Someone who is as committed to our life together as I am, that means housework, parenting, social life, financially, the lot. We have the same aims in mind and are good at working together to get there.
Someone to play with. We can be super silly together and that is important to me.
He shares many of my interests and his likes that differ from mine are complementary (for example, I like knitting, he likes making electronic gadgets, but we both enjoy creating something).
We have a great sex life.
He enjoys talking with me and I enjoy talking to him. We talk about everything, all of the time.
He is quite happy to call me out on dickish behaviour, I do the same for him. It makes us both better people.
He is a real grown up - so many men (including my exH) just aren't.
He is a wonderful emotional support. Recently I had a 'threatened miscarriage' at 13 weeks and he was logically supportive in a way that suits me perfectly.
He makes me feel loved. Really properly feel it.
We have our problems, totally, but the basics of our relationship are super solid.
