feel so disrespected...

sorry of this is long but i need some advice.. i may get judged for this but so be it. lately ive been feeling my husband has grown distant with me. he doesn't do the things he used to. when we "make love" it's like he just wants to hurry up and get it over with so he can go to sleep. I've also noticed he had been hanging on to his phone for dear life. meaning he will not leave the room without it. its on him when he goes to the bathroom to piss. when he goes and takes a shower. everywhere. and if he left it somewhere he would go back and get it and take it with him. hes on it constantly. but the moment i come near he shuts it off. so i said fuck it.. im logging into his fb.. now thats the part i may get judged for but quite frankly i dont care. in his messages i seen that he was talking to one of his friends about very inappropriate things. them sending gifs to eachother of naked women and talking about how this other dude (his friend) gets so much pus*y. and it just made me feel so disrespected. how would you ladies feel? i mean he would flip if i were to be talking to any of my friends about di*k and sending gifs of them. he would flip the f out. what are yalls thoughts?
