When trying to figure out what a man's intentions are, don't listen to his words---watch what he actually does. He's not treating you like someone he wants to marry, he's treating you more like a "friend with benefits." He's keeping you hooked by saying he wants kids, etc., but his actions tell you that there is no substance behind his words. Men learn early on what women want to hear, and if saying the right words enables them to get sex without actually having to commit, they will say almost anything a woman wants to hear.
Rather than feel rejected by him, I'd advise you to reject him, and wait for a man who shows you he wants to be with you--not sleep at his mate's house when he could be with you and your daughter.
Before getting involved in another relationship, there are two books that are must reading to help you find a man who will move the moon and stars to be with you.
The first is Temptations of the Single Girl This book should be required reading for all women before they start to date. The "temptations" are thinking that we can change a man or his behavior, settling for a man who doesn't want a commitment when we really want marriage at some point, and wasting time with the wrong man because we're afraid to be alone.
The second book is a bigger commitment. It's seven weeks of daily reading and writing and self-exploration. It will help you get clear on what you really want from life and relationships, and increase your self-esteem. Don't just read it all the way through. Do it the way it was designed--daily--and you'll be amazed at how much clearer this all seems at the end of the process. Calling In The One: 7 Weeks to Attract the Love of Your Life.
