I had the same issue with my H as he was able to show attention and affection to our children and not me. Actually I was being ignored and my presence not even acknowledged. Some months later I found out that he was phoning other women & corresponding on the internet during that time.
My C made a good point when I brought up the issue about showing attention to our children. Children, especially young ones, are easy to get along with. Their love is unconditional and there are no issues, past or present to deal with. Animals are simliar...why...Dogs are man's best friend. They can't talk!!!
On that issue...be glad that your H is being a good father to your S. Don't take it personally...even though there are some things going on.
THere are some interesting things in the SExual Issues Forum under the subject of porn. Interestingly the DB folks talk about the damage that it does to R. You can read some good things over there.
In every M one S is higher drive than the other. And humans can talk...so there are issues to deal with. It is easier to sweep stuff under the rug, pretend ...and "escape".
Your H "disengaged" present actions toward you suggested to me that rather than him deal with whatever issues in your R are troubling him...he is escaping.
Is your H at the place that he cares what would make you feel loved or desired?
