Last night was very difficult with S3 .5. He was very difficult to deal with and only wanted mommy to do everything. She was exhausted from being on her out-of-town business trip. I helped as much as I could. Cooked dinner clean the kitchen. I told him good night and she put him to bed she came down and got in bed and I went in and told her good night with a pat on the leg I said sleep well and left the room. I went to exercise and noticed there was a problem with the pan under the air conditioning. I think I fixed the problem, however, there was a lot of water. I went back upstairs to the bedroom and told her of the problem. Now we are divorced I have a new house closing soon and she will have to make any repairs on this home needed before sale. I told her that I need to go to the store and buy some things to fix the problem. Again just trying to be the guy that she'll need some day.
This morning I double checked everything pierced to be okay. I went upstairs to wake up S3 .5 and brought him down half-asleep. Walked over to her in the kitchen and said good morning. She turned around and if she did I turn so she could see his face she told him good morning and gave him a kiss and then reached around him with one arm and meet with the other and hugged us both from my back. I thought it would just be a quick hug and of course didn't feel much about it although I want to hug her back. She held us for a bit of time and then let us go to go get ready for the day. On the way out of the house today I told her have a great day and I hope everything worked out with your realtor that was coming to see the home today. She's excited for me in my new home but it feels weird to me.I know I'm being the better person and doing everything right before my exit. Once I am out I will go dark through the holidays. I do know that I will be invited to do things with her family as my S 10 wants to see them. Most of them are from out of town so I'm sure there will be a weekend or two of seeing her. This is so awkward and at the same time bittersweet.
