Just A Mom

I have a wonderful 3year old boy.. I have sacrificed my life since he was born, I did the best I could and I keep trying. We get along great and I love him to pieces... But, I have recently seperated with my husband who neglected both my needs as well as my sons.. He went back to his parents and comes to visit our son about once a week, not so much because he misses him and loves but because his mommy (my mother in law ) tells him to do so. He does not ask if we need anything and doesn't provide anything. I gave up my job to raise my son and now I am being supported by my parents... I feel useless and a big burden for them... I'm trying to find a job but it hasn't been easy.. But my problem is that my son is soooo happy to see his father and my in laws when he sees them that he totally ignores my existence..... That hurts me like hell!!! Nothing has ever gotten to me so much. I'm trying to respect his right to see his father but I'm running out of patience and strength and to be honest I hate the site of him and his parents... It's starting to interfere with my relationship with my son... I feel like he loves me only because they are not around, and they are sooooo fake a 3year old can easily be deceived by their charm. I love my son so much that if it were in his best interest I would consider giving him up, but thay are terrible not at all a good environment for a child, I feel so let down by my son when he chooses to ignore my existence when they around. I don't know what to do. Please if anyone has anything to suggest, or comment you might see something I don't....
