I'm 19 years old and my partner has just proposed to me. I love him/her but is this too big a step?

My partner doesn't help out around the house. He/she doesn't cook, clean or help fixing anything.

My partner told me he/she didn't want anything for Valentine's Day so I didn't get him/her anything. He/she got upset.

My best friend told me that my partner came on to him/her when he/she was really drunk.

My partner used to be really romantic but has stopped making the effort.

I lent my partner $1000 and he/she hasn't paid me back yet and he/she hasn't mentioned anything about it for weeks.

My partner called out his/her ex's name when sleeping.

My partner has to go on a business trip with his/her ex, they will be staying in the same hotel. He/she told me that he/she has no feeling for the ex.

My partner invited me to move in with him/her but I'm not sure. I don't want to hurt his/her feelings.

I've fallen in love with my best friend but he/she isn't interested.

My partner's personal hygiene standards have slipped.

My partner's parents are always dropping hints about wedding bells and the pitter patter of tiny feet.

My partner's mother won't leave him/her alone. She insists on doing all his/her laundry and that they go out together. How do I make her back off?
