I’m big mad😡

So I’m now in my third trimester, I buy everything for my son . But his dad hasn’t buy anything at all. He hasn’t seen me since I was 10 weeks but that was for 10 mins and that’s it. Btw he has a son he lives with the baby mama so he’s with him 24:7. I ask if he can come to visit me or help me go shopping for the baby. He said he can’t that he wants to spend time with his son as much as he can. I said if I can come over he said he doesn’t want to “ stir the pot” Like I get it but he lives with them! He hasn’t seen me for so long it’s like we’re basically strangers. Idk if it’s my hormones but would you guys get mad also????
