how do i care more about myself?

and not my husband? he never gives me attention anymore, yet he always gives his attention to other women, whether in public or in tv/social media. he does it in front of me carelessly. ive found myself competing w them for his attention, but i always lose. id talk to him about it and hes just like, why cant i just look out for my surroundings? but hell, he always, and only checks out young, asian women and thick white women. he doesnt even want sex w me anymore! i want it a lot but only get it 2x a mth. but goes to porn a lot and not only that checks out women online. not dating sites. idk anymore, like hes no longer attracted to me, idk who i am to him for him to do that to me. how do i forget about this shit and just focus on me? im a sahm and all i do is stay home :( this is why hes so used to me and no longer thinks im attractive.
