I’m 19 and my partner is 22. I’m 8 months pregnant with our first baby and we have recently moved into our first home.
Pregnancy has been good - it brought me very close to MIL at first, and I thought living together would work really well as we spent pretty much all our time staying at each other’s house before. But I’m beginning to think it was a really bad idea 
To give a bit of background, his family live 2 streets down and most of his friends live around here. My family live further away and I have about 2 friends left, who don’t live locally. Every single day one of his friends turns up, and never leaves! He spends all his time downstairs with his friends when they finish work, sometimes till late at night.At first I didn’t mind them coming every now and again, but over the last few weeks it’s become more and more frequent. I’ve told him that it’s fine that his friends come, but I’m heavily pregnant, I’m tired and I want to spend some evenings together and make the most of the time we have now. I’m also so worried this will happen when the baby is here, yet he insists it won’t. He argues that he’s entitled to some “time with the lads” as he’s having a baby soon, and it’s his house too. I told him I understand that, but it’s not fair when we rarely spend any time together yet live together.
Another issue is how he tries to please his family so much, more so his mother. She was a crap mother to him, which they both admit. I feel sorry for him because she uses him for childcare for her younger children, and makes him feel guilty when he doesn’t/can’t babysit for her, so he tries his best to please her (for example once I was at triage because I had a scare but he didn’t go with me because his mother insisted it was nothing and he should watch his siblings). She never comes round to the house herself, never asks how either of us are since we moved in together (yet before we did she was like my best friend! We used to always speak), she basically only bothers with him when she needs a favour (childcare, going to the shop for her, walking her dog). He just can’t seem to realise shes using him, yet everyone else does. Even his cousin mentioned it to him how his mum never really bothers with him. Yet he defends her every time.
We also fall out because his younger sisters (aged 10 and 5) are constantly knocking on our front door to come and see me. They will knock after school, then knock around 9pm when they are going home from playing out (which I think is too late anyway which caused another argument when I said they are too young to be walking around this area at that time). They are lovely girls, but when I’ve had a long day or I’m busy doing something and I tell them I’m sorry I’m busy today, he goes mad at me saying I’ve let them down etc.
I just feel like our relationship has lost that excitement it had at the beginning and before we moved in together, as were both young we used to have sex all the time 
but now with being heavily pregnant most of the time I just can’t be bothered or I’m not in the mood for it. So he falls out with me and says he misses how it was before. We still have sex every few days but it’s just not the same anymore because like I said we barely spend time together, and when we do there’s always a knock at the door from his siblings or his friends.
I hope this makes sense and isn’t a baby brain rambling but I just feel so sad. I feel selfish to want some time alone with him more often and feel like I’m pulling him away from his family and friends, but at the same time I feel like they don’t need to come round every single evening. I’m writing all this because he’s so hot headed and always believes he is right, so if I say that I don’t want his friends/family to come round today, he assumes that I don’t like them, I’m really nasty to turn away his little sisters etc... and it just causes an argument. I don’t know what to do but we can’t carry on like this, I’ve been thinking of writing out all these thoughts and sending them to him so maybe he can process what I’m saying easier but I don’t know whether that would completely fuck things up 💔
