L.F.
I feel your pain - I have been there as well. I got to the point to where I had to kick my daughters father out when she was about the same age as your child.
If you are okay with your babys father picking up your child from daycare on Friday and then dropping the baby off again on Monday morning - whenever you agree the temporary vistation will be - prior to the courts setting it up.
The standard visitation in Texas is typically the 1st, 3rd and 5th weekend plus every thursday from 6-8 usually.
for now I would mention the weekend arrangement and see if that would work for hte both of you - if you are agreeable to it.
Good luck and I am here if you need to talk.
Maybe once you get to the point of letting the hurt go - the lines of communication will open again between you two and your son will see the separation was for the best - if he ever questions it at all.
NEVER speak ill of yous ex in front of him. Always tell your son his father loves him - if you dont have a answer you feel would otherwise suit the situation without harming their relationship or yours with your son. Eventually if things go south with your son and your ex (which I hope they do not) let your son form his own opinion.
My daughter is almost 6 - her father doesnt pay child support and doesnt visit except for when it suits his needs. I allow her to make the decision of when she wants to see him and when she doesnt on those attempts. I do not discuss the child support with her at all. When she asks why he doesnt come around I simply say he is busy. One day she will understand that other things were more important to him - like his beer or his friends or whatever it was that kept him away and whatever excuse he uses for the day. Kids are smarter that we give them credit for at times. Just give your son all the love and support you can.
