No libido...4m pp

So I am 4 months postpartum... my boyfriend and I have had sex once in that time frame. I have basically no libido. I have very slight urges but I mean so slight... and they usually fade before I get the chance to act on it. My bf basically yelled at me last night he doesnt know where our relationship is going anymore, hes fed up.. he feels unattractive etc.we have been together for 10 years and have a rule we dont "take care of outselves" because we have each other and he basically said he was going to start doing that which honestly broke my heart. I have told him several time he has to romance me I have to be turned on to do anything other wise it's basically rape feely... he said he wants to be romanced too. Why cant he be romanced too he want to be romanced....he hasnt tried anything outright to romance me or try to turn me on, I apparently have to romance him which does nothing for my side of this... I told him weeks ago when it was first brought up I cant just flip a switch. So basically I feel like I have to let him do whatever he needs to me so that i dont lose him because hes not taking the initiative to just try to get me going he said after all his stress and working all day he just wants something to be easy.... honestly upset me quite a bit too... we have been together 10 years in May this is out of character for him we have two children together... I'm at a loss... he says my low libido is bullshit that im lying ,not sure why he would even think that. I'm breastfeeding exclusively also...

Any tips on ways to increase my libido? I even tried to watch freaking porn this morning (have not done that in basically 10 years) and honestly didnt do much for me.. I feel like a nonsexual being...

What do I say to him?

Any help with any of this would be great..
