You are stronger than you think.
You have been a single mum, coped with childbirth, you are repairing yourself after the tragic death of your mum and you are still functioning, working etc when your twat of an ex left you during a high risk pregnancy.
You ARE strong and you CAN do this.
Make a Facebook/snapchat / whatever app - group/group message of your closest friends and family . Tell them you are going to need help and support, list dates of appointments and ask for people to come with you. Ask if anybody is willing to be your birth partner. Ask if there’s anybody who can stay with you for a few days after you come home as you will need help. If you ASK like this it’s amazing the amount of support you will find is out there.
I wouldn’t be communicating with ex or his mum until after the birth.
I would message them telling them that you are finding the request to return a gift and the threats of court too stressful when you are high risk and as a consequence of their actions you have decided to have no communication with them and you will advise them when the baby has arrived and when they may visit.
Then I would block them both. Advise your midwife what you have done and tell her you want them both banned from visiting you or baby in hospital ( in case they somehow hear you have gone in).
Obs, like everybod6 else has said , use your surname.
And because I’m a right control freak/bitch do you know what else I would do?
If you have chosen your daughters name with him then bin it and choose one YOU want. You know that YOU are going to be your daughters main parent, the one she lives with. You and she are a team ( with your little boy) and who knows if your ex will even be in your daughters life in five/ten years time. So why give her a name that will remind you of him. Pick what YOU WANT. I would.
Register her with her new name and your surname. Show that you mean business and when he left you BOTH ( because he didn’t just leave you - he left her too. If he was ‘ all that’ as a father or as he seems to think he is then he would have stayed with you until she was born at the very least) he resigned his duties towards her.
You three will be a great team. Think of your mums strength and channel that into you. You have her blood in your veins - the strength is there, you just need to tap into this.
You can do this. And if you need someone to come on Monday I’m free all day , I have a car and it’s got a full fuel tank.
And get someone to take the cot apart and drop it at their house.
Just dropped in front of the door in a heap.
Good luck. Please please keep us updated .
I think a few of us feel emotionally invested in this tread. You have lots of strong w9men supporting you on here.
