You are not invisible to me! As this video explains--with some people--trying too hard and serving others all of the time doesn't make them love us. I have stopped giving so much to people who do not do the same for me. Like you, my husband is my biggest supporter! I am so grateful for that! We are lucky to have good marriages. Focus on what is positive in your life. Focus on the people who do not make you feel invisible. Don't give energy to or think about anyone who makes you feel invisible. Everyone has had someone in their life who has disappointed them but we can slowly leave those things behind and focus on the people who are better matches for us. Not sure if this video applies but threw it in there anyways:

TO GIVE YOUR ALL DOESN'T MAKE YOU MORE LOVED!
