K., it is not difficult to see how your feelings could be hurt here. Please realize his actions say otherwise. At this point in his life, he sees daddy - swho is not hom all of the time- as the good guy. So he rewards him with the words. But believe me, if there were a situation where he had tostay wiht someone else while daddy was out working- he would want his mommy! If you are that desperate- arrange for that for a week or whatever- but not just with anyone.(rules need apply- not a place where he gets whatever he wants whenever he want, etc...)
But if you just go along with life, doinghte best you can, and the bothe of you showing love, you continue to tell him you love him, eventually, he will reciprocate it. For now, just know that he insn't sure of all of the meaning of what he is telling you, and he may be SO close to you, that he doesn't realize his true feelings for you.
Of course he loves you, and it is natural for you to love to hear it. I am sorry it is how it is right now, but please know it won't stay like this for very much longer.
Also, if you have guilt about your reactions to him, then maybe watch super nanny with your son. Follow how she does things and be confident about your parenting. Parental guilt is almost always a guarentee while being a parent, but if you truly feel that much guild, watch the show. You do need to be sure that how you parent is right.
Also, go to the libraby and read some books together about this sort of thing....maybe look on line for books tht will get your son to understand mommy wants to be loved too.
I hope everything works out very soon to where Nolan understands and appreciates his mommy that loves him so much.
God Bless,
A.
