Are maybes bad? Not necessarily- they mean you are giving someone a chance, opening up your horizons, loosening your list of must haves, growing up. But is it possible that you might say maybe just too many times with this particular guy? Is it possible that you want to be in a relationship so badly that you are pretty much overlooking everything?
Relationships are hard and no one is perfect but someone who you choose to spend the rest of your life with should have a lot of yeses, very few nos and just a couple of maybes. If you base your whole relationship on a maybe, you are never going to know if the relationship can work until it is too late.
So don't wait six months to sleep with him because he has small hands and you are worried that his you know what is going to be microscopic; take a look/see now and see just how bad it is FOR YOU, it might not be so bad.
And don't wait six months to tell him that he becomes a rude bastard when he is drinking, tell him now and see if he can curb his drinking or curb his mouth.
And don't wait six months to ask him what he really does for work, ask him now because if he doesn't have a real job or doesn't make any money to speak of, you need to decide now if you are in a mental and economic place to support yourself, your future children and him.
Then, if some of your maybes become flat out "no's", do the right thing for yourself and move on. Contrary to what some people might tell you, what you see right now, is what you are going to get.
So make sure that you want it, all of it. Otherwise you are just throwing in that "single towel" upon which you have held onto so closely for a maybe, and we all know deep down what a maybe really means.
