Short Trip To Misery

Ok, so the title is a bit melodramatic. I probably am more angry, sad, and lonely than miserable. We have only been married 2 1/2 years but they have been some of the loneliest years of my life. My husband had an 11 year old son, now almost 14. His son is his life and I am invisible. I call them Mr. and Mr. "Jones". They do everything together: shower, use the same towel. Husband forgot our last anniversary even though I talked about it and built it up for weeks but the night before he took his son to dinner and a movie. He won't leave his son with anyone ever not even once to spend time with me. It's the two of them always. The now 14 y/o can't go to sleep by himself so hubby goes in there every night at 9, watches TV and plays on the iPad , falls asleep in the recliner and doesn't come out till i'm asleep. It's a Ridiculous farce of a marriage.
