Mother/father separate baby showers storyfollows

I honestly don't want to be in the same room with his friends and family. My ex has been fake with me from the beginning. Liar and a cheater . Shitty personalty too. Some of his family is ghetto .  I honestly don't see us getting good gifts from his side. I'll be so embarrassed to at the lack of gifts. I'm concerned it'll be a free food and drinks event.  I'd have to be the one dropping more money for the shower because I make more. It's not worth it to drop money on food and decor and a place to rent. Me and him aren't on good terms right now but he wants a baby shower. He's still involved with The  pregnancy so far.
