I don't really know where to start. Please be gentle as I've been in tears over this.
Been in a relationship for a year with a guy. Knew him for a few years before that. Always got on well so when we went out for a coffee and it went from there we were happy. We had about a month honeymoon stage. My Mom died at the start of the year and he was there for me. He changed jobs which was moving up a Higher position and his mum is a hoarder, so stress from his side too. I've recently moved into a 2 bedroom house for my DS and I after living in temporary housing for a couple of years so I was over the moon that finally after Covid19 and my Mom dying that something good was happening.
Before that we had petty argued a fair bit, just petty not rows. His Mom knew this and I stayed at theirs the night before the funeral. His Mom got quite questiony about our relationship and I said it's my Mom's funeral tomorrow please can we not speak about this now. And she raised her voice at me so I walked off upstairs to where my DS was sleeping. My OH wasn't present as he was on his way home from work but his Mom told him the same story as this when he arrived home and he admitted she was wrong as it was the night before funeral. I never got an apology. 5 mins before we were leaving the funeral I said ill go check on OH to see if he's ready and she got stern at me again calling me controlling when actually I was just going to check he was okay getting ready upstairs.
I spent a lot of money on a wardrobe for my bedroom which OH kindly offered to build for me. It's unstable, wonky, and cannot be fixed. The doors aren't lined up properly. When we was building it he bashed my ceiling which now had a massive noticeable dent in it which he blamed the builders cheap paint 
(it's new build house) and he just has no care about anything in my house.
He is a very serious person due to his job and does smile but not as often as a normal person. He asks why if I don't want to have sex or if I don't want to do something specific in the bedroom. Constantly telling me how to drive, today as soon as the car in front of me started moving in traffic he was questioning me why I took so long to start driving
He has helped me financially. He paid for my bed for me as I didn't have one and said I could pay him back but after him not doing my wardrobe properly and denting my ceiling, I spent 25£ on a flower bouquet for his Mom on her birthday a few weeks before she made the comments.
I've probably answered my own question and just to leave him. But I don't know why I'm so scared to. Maybe because I'm grieving over my Mom and I'm blaming myself for not thinking straight. There are other examples but are too outing. I've spoken to a therapist and she said what I've told her is what she hears from couples that have been together for 10 years not 1 year.
