I sympathized with you in your present predicament. May be you should be grateful that you get to know what's going on with your man now. What if it happens after you are married to him? I want you to listen to your spirit. The answer is there. Being in denial is understandable, going by how long you've been with him but I am not sure there's anything left for you with this man if he's so intimate with another woman who could use his phone to text you. Cheer up and see what God will do for you.
