So you have a 1 year old and been with your BF for 6 months, so you got together when your child was 6 months old, is that right ?
Your comments seem a bit disjointed, are you ok?
I don't think your issue is being a parent, it sounds like it is the relationship you are in that may not be working.
He most likely is very tired after a long days work, but At 6 months in, I was very excited to see my boyfriend and we chatted a lot, but I also wasn't dealing with a 6month/12 month old.
You shouldn't have to dress up nice for him, you should dress for you. Dress to make yourself feel nice, give yourself confidence, it's only a bonus if he likes it.
Without sounding horrible, you need to concentrate on your child and you. It shouldn't be hard work 6 months in. You never really know anyone, in my opinion, until you live with them. If you are not happy now, sadly I'm not sure how things would change going forward, sorry.
