Time – Don’t waste it.
You are ready for marriage. Now it means finding someone who feels the same way and not just to date for a relationship, that could lead to marriage down the road. If you are serious, then when you are speaking with people let them know this.
You should be on the same “page” with the person you are dating. But if you see that after about 6 months the relationship isn’t going anywhere, then maybe it is time to talk to each other and see what is going on. If you are really serious, then don’t waste time being with someone who isn’t.
I also say, if you decide to “walk” and it was meant to be, then the person will come back and maybe make the final committment to you.
