Is he sleeping with another women?

For some reason my ex boyfriend who I’m currently pregnant with I’m (26weeks pregnant) stopped having sex with me sept 12th. He never goes weeks without having sex and would bug me about it but lately he’s been shaving down there.. and he’s not the one to shave to often or to worried about how he looks down there... then I remember trying to ask him about the situation why it’s been 3weeks long and he hasn’t been intimate with me? It’s not fair.. 😢 if he’s getting it somewhere else... and I’m here like an idiot pregnant and not getting anything at all, wtf do I do?

We finally had sex oct,15th and have not had sex Since then .. but that was only 1 time since the time we had sex on sept,12th....

He’s sleeping with someone isn’t he...? He Denys it but nothing adds up, this is all new...

Also we have two other kids together and both those pregnancies we always had sex the entire pregnancies and now its like I don’t exist .. 😭

Advice please...
