I’m so torn

So me and my husband have been married 1 years and have baby 4 on the way. Every since we got married up until about 2 years ago our marriage was great. But now we maybe have sex twice a month, we never say I love you and sometimes when I do say it it feels forced for him to say it back. We’ve been finally able to talk when he knows I’m upset and I’ve told him I NEED more intimacy. Even if not sex, more kissing, hugging or just flirting or nice text thru the day. I get nothing. It will be good for a few days then of course goes back to the way it was. I don’t want this type of marriage where we are pretty much roommates raising children. He’s the best dad and I know he loves me cuz when I’ve left for a week or two before because of this he’s devastated, but not enough for him to change obviously. I’m just sick of not feeling loved or good enough. I’m sick of forcing my husband to act like he wants to be intimate with me or act like he loves me like he says he does. Therapy is off the table because he absolutely refuses it. Idk what else to do. I always feel so sad and bad about myself.
