House move but feeling excluded

[Cookingwithflo]

I really don't know what to do, my partner and I recently found out that we are expecting our first baby and that we have been successful in a new property and are due to move in on Saturday. His mum is going to help him move (I was not included in the conversation) we are currently living with his parents as we needed somewhere to stay until we found another flat and they had offered (they also never communicate with me or even let me leave the bedroom without an attitude so this stops me from even being able to eat during days again whilst pregnant) . I paid the rent and deposit because my partner was short as he had to pay his mum money and our car and storage came out the day before. During all viewings we have had, I am forced to sit in the back of the car. I am extremely grateful for a lift as the viewings fell on days my partner was working and didn't have time to drive home to pick me up then drive back and fourth on a break so we had asked if she was okay to help us out as it would mean we are out of her hair. After each viewing I was again forced to sit in the back, unable to express my feelings on the property. She would barrel question upon question but I didn't even have time to discuss with my partner, then when he came home from work she would talk to him in another room where again I am excluded. I feel like this move will be me sat alone at either house waiting for them each trip, again excluded. I really don't know what to do, this was supposed to be nice but it's been ruined for me personally. Maybe it's just the hormones but I've received attitude from my partner when I got upset and expressed my feelings about this situation.

Umm in the kindest possible way, pit on your big girl pants and please leave this situation.

Why on earth are you allowing someone to treat you that way? Walk away!

Hes said he can't choose how they act, I know we have tried to solve their issues in the past but I just do not want her to be part of the move. Do you have any advice on how I could maybe put that across?

I'm not quite clear, are you saying that you are relying on her for lifts and accommodation? Or that your DP is driving and she is sitting in the front seat ?
Anyway, time to be assertive. Step in start getting involved with the agents/landlord/whoever is arranging the viewings, and tell your DP that as this is to be your home, you get to voice your views. What is actually stopping you? Is it that they are both just opinionated and you can't get a word in edgeways? In which case speak up!
Sounds like he is used to his Mum running his life for him, you have to tell him that's not how it's going to be going forward.
Don't sit there passively, waiting to be asked. Talk over them if you have to, to make yourself heard. Be the one who makes the arrangements. You can make your own way without having to get lifts, and make learning to drive a priority, so it is not always you sitting in the back. And no one has a right to the front seat, in many cultures it is the older person who gets to sit in the front, in some it is the partner of the driver, but it doesn't always have to be that way.

Sorry but you need to stop being such a wet blanket. Assert yourself to your partner and your MIL now because it will only get worse once the baby arrives

that we have been successful in a new property and are due to move in on Saturday. His mum is going to help him move

You need to grow a pair. Stand up literally and TELL his mother that you are grateful for her offer to help you move out. (If you've been staying there then anything else is rude)
Then tell her and your partner what YOU would her to help with on moving day. Be sure and flag at some point that YOU have received confirmation that YOUR funds have been received for the flat.

If you don't do this you are laying the whole basis of a subservient relationship to them both for the future.
