Just a side-note. I do not believe that we all say what we truly think or feel when drunk or in pain.
I believe that some of us actually lash out and say things just to hurt the other person or the 'pull the hurt' out of ourselves and that later on, we wish that we could take it back.
I am not defending anyone or condemning anyone...I am just saying, if the relationship is not good then it probably will not improve with a disease but it the relationship is good, fundamentally speaking, then do not allow one stupid comment to wash the whole thing out to sea.
The other point is, sometimes we know exactly what we are getting into and with whom we are getting involved and in spite of that niggling feeling of fear or dread, we do it anyway.
We have our reasons.
It could be just a night of comfort or pleasure or it could be a need for companionship when we feel most vulnerable or alone in this world.
The night turns into 2 or 2 weeks or months or years and we get used to having someone around, good or bad, we accept the bad in order to have some good in our lives.
It might not be ideal or great but it is better than nothing at all (the French have a saying, better to be alone than in bad company, but that does not apply to everyone...some of us prefer bad company to no company at all).
So, think about what you are doing and why...and decide according to your needs...today and for the future.
By the way, You did not ruin any part of his life, he is neither attached by chains to a wall nor is he married to you with a contract...you are both free...so if he has stuck around with a 'sickie' he has done it freely and without constraint...and must find something 'good' to keep him coming back.
Just an opinion
