We share custody, our son is with me one week and with his dad the next week. I carry the insurance and we are supposed to split the expenses. I hate this arrangement but it seems to be working so far. As much as I hate to admit it a boy does need his dad. It seems like ex uses it as an excuse to see me and spend time with me. I'm trying to be fair ,but would prefer for ex to be completely vaporized. Instead, he's coming back to work at the same place as me. I didn't care for it when i loved him.....I really don't like it now.
