I need advice. I'm thinking of saving up money to move my partner and I to our own place but I may use the money to leave them quickly when the time comes because they haven't been loyal.
That's a major decision, would you prefer to use the money to leave rather than stay with your partner?
Yes, I think I would. I've been planning it for a while. But if something goes wrong I'll have to put the plan on hold.
If your partner has been disloyal and you are upset by that, then it would be best to make a clean break of the relationship rather than letting them think you are going to move in together. It is a waste of time and money to stay with someone you know you'll leave eventually, so you should just go ahead and do it.
I knew you wouldn't understand it.
It sounds like you have a pretty major life decision to deal with. I think you may be better off letting your partner know you aren't okay with them being unfaithful and figure out what is best together.
