Husband not interested in sex after me giving birth and is not affectionate?

all evenings he watches tv/movies and those few hours i have free in the evening we could spend on US are wasted. i told him few times i feel neglected but he gets angry and insists we do spend time together when we go for a walk with the pram, play with baby, go out for lunch etc. he says if i wanna be with him in the evening i should join him on the sofa in front of tv/computer watching what he is watching - mostly action movies because we can't go anywhere in the evening anyway. because of the baby there is nothing to do except watching tv we can't go out. so basically i have to initiate oral sex on him to switch the tv off if i want some intimacy. i am fine with oral sex but the fact that it's always me who needs to do the first step and it's always in the same dull setting - i am not very excited about it. I am still not ready for proper sex (3 months after delivery) But his attitude puts me off anyway...Am i doing smth wrong here? how can i make him interested in me? there is a lot of hidden resentment builing up. our relationship was never one of those perfect ones 'made for each other' type...we did have a lot of problems in the past (including sexuality when he basically stopped initiating sex) but i thought it was slowly getting better. i am contemplating on leaving him but our little girl would be without father if i do this. i would need to move back home to another country if i do this and she would hardly see him then.
