Been married for 3 years with my husband for 14 years total..

We have a 9 year old, 2 year old and 9 month old.. I want about her child he doesn’t.. he wants to get a vasectomy.. for the last 3 months he’s been very distant.. doesn’t sleep in the same bed as me, he will use the excuse that he was too tired to come into our bed.. we had sex only twice this month.. I’ve asked why he said he’s tired or that sex isn’t everything or that he doesn’t want to get me pregnant.. so I suggested condoned he says he doesn’t want to use them..

Idk how I’m feeling but im starting to feel like he isn’t into me.. I’ve suggested dates nights or just trying to watch tv together but he says he’s tired.. I’ve kinda given up.. not sure what else to do.. not feeling wanted by your spouse is a very disheartening feeling.
