Not setting a date? 😒👰🏽

Sarah-Jane • TTC 16 months💏We did it🤰🏽Sophie born 10/7/18💕
Ok so been with my fiancé for 6 years soon and engaged for 2 and half. 10 months ago he decided we should have a baby (I have a 10 year old from my previous long term relationship) and was like ok that's great
Long story short he had a condition that will make it near impossible to get preg naturally and next step is IVF which I would go through a million times to get our baby
We had a chemical pregnancy last week and he was there for me and really lovely. He's normally a bit heartless to situations as he doesn't ever show any emotions. I just have been thinking this is def the man I want to marry and asked him this morning about setting a date, he bacisally made a joke about it and said no then compared me to this girl that's marrying his best friend that wanted everything in a year and is like a gold digger! I'm gutted, I work have my own money and have never rushed 'us'.
Not sure what to do now I feel a bit angry AND stupid now!
