Top 3 reasons why if you have to ask your partner to do the following, they are not for you!
1. Sharing expenses
If you and your partner live together, and one doesn't contribute at all for the duration of the relationship, then this person isn't for you. If you have to ask and explain that finances are expensive and that one person shouldn't be upholding 2 people (unless there are special circumstances etc) then this person isn't for you.
2. Talking down to you
If you have to ask your partner to not talk down to you like a child, or an unintelligent person then you are not with the right person. Unless there is a heated fight and an apology follows after- no one should be spoken down to.
3. Being nice to you
This one is so obvious. If you have to ask your partner to be nice to you, or be affectionate or give you time and attention- then you're really asking for something that should be provided.
