I’m so done

I told my mum about it and she lives nearby. I made her promised me she won't tell my brother by now. I want to do things as best as possible.
The only option is him going out of the flat, because even when he contributed with the arrangements, it belongs to me, so I want to be fair with him and talk to him to give him a good way out.

The best of all and I thanks god for this is that we don't have kids even when it was his dream, I rejected that possibility partly because of my psychological issues and partly because I don't consider him the right person to rise a kid. At least, not with me as a couple and the circumstances under. I don't want to make him seem a horrible person but I saw his attitude with my nieces and nephew and I could say they are more mature than him. So, at least, no kid is gonna suffer or suffered.

I was very clear in how the situation was unsustainable. I offered him an amity separation. I don’t want anything bad can happen to him. I want the best for him.
We have two doggies, they are our kids, no kidding, they are and I offered him to help him with his rent because he contributed a lot to the arrangements in the flat I’m still paying and that he could spend all the time he needed with the doggies.
He kept telling me that I was his life and that he doesn’t want a separation. He was gonna change. He was not going to pick up my phone and he’s gonna trust me.

I’m in a mess, actually. The opportunity to have him working out along the week, gave me a peace, a relief I hadn’t have in years.
My heart tell me that he’s a nice person but my guts tell me that I’m better without him.
He cried but I didn’t see tears.

I feel myself each day colder with him.
