What???? This is wrong on so many different levels. Let me first say that being abandoned as a child will deeply effect how you interreact with others and life in general. You need to learn to love yourself. You don't need anyone to make you feel loved in life. It may take you another decade to figure this out, but I hope not.
My first reaction is, who the hell does this woman, your wife, thinks she is telling you and being with another man traveling the country, but at the same time telling you that she doesn't want you to have a baby with another woman. However on the other hand you are doing the same damn thing. If you really want your wife back, which obviously you do, you would stop dating other women all together. Crazy! Hopefully she will come to her senses.
