Should i have told my family and friends ? I feel really guilty about telling my friends as have i betrayed my children by talking about their Dad .
What nonsense! You have not 'betrayed your children'. You have spoken your truth. What you have told your friends and family will have no bearing on your children's relationship with their father. Did the same 'grass isn't greener' friend put that idea in your head?
One of my friends said " maybe the grass isn't greener being separated and probably be lonely forever.
But you're lonely NOW. Just because he is still in the house that certainly doesn't mean you aren't alone. There is nothing more 'alone' than being in a marriage where the trust and the love is gone. All he is is a body taking up space and a constant reminder of your current unhappiness. As I've said before it is better to be alone than be wishing you were.
As for lonely, you have friends and family. You can pick and choose activities and groups to join once you're out and free. You will be only as 'lonely' as you choose to be. And besides, you may actually enjoy the peace and freedom that comes from living on your own and making your own rules.
I'd say this 'friend' is either in a bad marriage herself and trying to justify staying OR she is living in the 1950s where a 'woman was nothing without a man'.
Sometimes i feel like im in a no win suitation as if i stay I'll never trust him again or forget what he done to me if i leave my children's home is broken .
Your children's 'home' is already 'broken'. And besides, your children are all adults and IIRC living on their own, other than the 17 yr old so exactly what 'home' are you 'breaking' for them. And the 17 year old is old enough to understand unhappy parents and divorce. Yes, I'm sure there will be emotions for them, but they will recover.
If the home is 'broken' then HE broke it. Your children are old enough to understand why you want to leave. I certainly would not have resented my mother for wanting out of a marriage where my father was a constant cheater, would you? I would have wanted my mother to be happy.
Make the decision that it right for YOU. Don't be a martyr. No one will thank you for it.
