OP I just don't understand the logic. You can't guarantee anything in a relationship as it is. I mean for example this guy your seeing now could be someone who waits but later down the line you move in together and the relationship becomes toxic, it's a possibilty that could happen.
Whenever you move a relationship on you always have take a leap of faith. I mean do whatever you want but remember that somewhere down the line you are taking a risk. Sometimes it will be a good risk you took, sometimes it will be a bad risk. That's life.
