My mom is going to give me a nervous breakdown 😰😰

Valerie
Ok this may be long...sorry for venting...So for starters my relationship with my mom is pretty close. I love her to death and am thankful for everything she's done for me. A little background I had my 1st son in 2008 and was in a horrible abusive relationship (married) at the time. He was in the army and got orders to go to Germany which I refused to go so anyway he left and I moved back with my mom when I was 6 months pregnant. When my son was a year n a half my husband at the time came back home and wanted to work things out n I was done with the abuse and finally held my ground and divorced him. I lived with my mom till my son was 2 and then got a place on our own. I have raised my son with no financial help from his donor, my family or government. 2 years ago I had to move out of state for work and moved from California to Arizona. I missed my family terribly and hated taking my son away from everything he knew. We were depressed and I was so lonely. I had never dated after I divorced because I never wanted to be the mom that brings men around their kids. I met my now husband a year n a half ago and I just instantly knew he was the one! My son loves him and calls him Dad so we got married and am now 35w3d with a baby girl on the way. So basically my breakdown is because my mom is having the hardest time accepting the fact that I don't need her in the same sense that I did when I was pregnant 9 years ago. This is my husbands first experience with having a baby and is so excited and my mom wants to come for a whole month to stay and I told her we wanted no visitors at the house prior to the baby coming and that when I go to the hospital that I would let everyone know and they can come at that time and she agreed but now is begging to come Oct 13th and stay through Halloween I told her no. She threw the biggest guilt trip and is driving me crazy! She finally agreed to come October 13th-20th and that she can come back the day before Halloween so she can trick or treat with my son but now she's still trying manipulate more time and called me today crying at how she doesn't want to miss anything and how she misses us and I miss her too but I have to respect my husband too and don't want visitors for a whole month!! What can I do or say to her that will make her understand that I love her and want her there for the birth but she can't just come and take over when she wants?! Sorry this is longer than I intended 😔 I will post screenshots of our text of when she 1st asked to come the 13th
