I think my man is mad bc im prego

OK let me start of by saying I think he's mad bc I'm the center of attention now and he's a mommas boy and ig that's not OK with it I involve him with everything I do so how would I go about to get him not to be so jealous? And he is also mad BC I don't want to do anything sexual anymore and he threaten to leave last night BC I don't want him shouldn't he take in consideration that I don't feel hood or I'm not up for it? Should I just give him what he wants this is my first pregnancy he already has one kid and I don't want him to leave me over him being ridiculous or maybe I'm the one being ridiculous?
