Here we go

Hi-I'm Maggie.   I am still married but my husband has turned to a different lifestyle.   He states he has needs that no "one" woman can give him what he needs.   He states he's not ready to let us go (but who knows if that's really true).   But he's tired of the fighting. Here's the thing.  He's felt this way for ten years.  I saw one of the numbers he was texting all of the time about two years ago.  I brought it up to his attention.  He told me at that time "I need to fix what's between my ears"...brain.  Then a year later he told me "what do you thing about a straight marriage versus open?"   I havn't dealt with it well.    And what's really bizzare (for me in dealing with this) is that his parents live with us.   So it's not as though I have all of the privacy in the world.   I have no idea what to do-what to say-I don't anything will change him.   I so wish there' was a pill that could make me not care.    I dont know why he keeps here-it must be for financial purposes and perhaps to apease his parents.   His parent are very nice.   His family are very nice as well.   I have very little family...and none here.   My kids are older (except my 11 year old).   I am no beauty queen.  I am 54.  I am in good health, I work hard, I am educated.  I'm not this billboard looking woman, but I have feelings, and I am made of flesh and blood.    I've never cheated on my husband.   I just need support.   I need a connection.   Sometimes I think "is God wanting me to take my own life?"   But then I can not do that to my kids.   I am lucky....I have healthy, beautiful, bright kids, I am healthy, and I still (knock on wood) have job.   I have a house.   I realize these things.   Any response would be appreciated.   Thank you for reading this.
