With my husband 21 years, married 7 years, living together 16 years - 4 children together youngest is 4 months old

14 years ago I heard a rumour my sister and husband were together, he denied it. I was always close to my sister, my husband always seemed to have a soft spot for her, sometimes I would think maybe something is going on here but i would dismiss it, she has a boyfriend and children but he does his own things at the weekend so her and the kids spend time with my family sometimes

3 weeks ago the 3 of us were having drinks together in my bungalow- we had a good night and went to bed, I drank a little more than usual so was a bit drunk. As far as I knew we were all tucked up in bed.

The kids slept in the 2 bedrooms, myself husband and baby in 1 bedroom, my sister and her youngest slept in pull-out double bed in sitting room

His story

He went out to the sitting room roll a smoke in the pitch dark with no runners on, no jocks on just tracksuit bottoms sitting at the end of her bed even though their were other seats available, the reason he went out was because I got sick

Left a dark room with me getting sick to do this smoke

I apparently leaned over him to get sick

Could not get smokes and come back to dark room where I was getting sick to do a smoke in pitch dark because wife was getting sick

Said no jocks on him cause I got sick on them but wore them that day, later said he didnt say it

Apparently I got sick on his runners, no sick visible on runners wore them the next day could of worn other runners with no sick

My story

Although I was drunk I know I was alone getting sick, first got little sick in bed with no-one beside me, was able to slide over and get sick on floor husbands side no runners visible but jocks in corner

Realised husband was'nt there went out to see where he was 

Caught

I went into pitch dark sitting room

Sees husband leaning/partially lying on bed

I said what the fuck are youse doing

Husband leans up from bed

I went over to switch on light

I Try to pull covers off the bed, being stopped by husband

Get covers off bed she has no knickers on or bottoms

I start to choke her, he stops me, he gets boxed

This gives her time to get knickers and bottoms on

Boxing her, husband is stopping me

Daughter comes out and gets involved in scuffle, she gets boxed in the nose and beer poured over her head by her dad so she sits down.

Sister pulls my hair down to bed, husband doesnt stop her but yet stops me hitting her

Sisters story

She was asleep

She doesnt know why he was in the  room

Questions I asked him for clarity

Why go out to do a smoke in the pitch dark 

He says it wasnt pitch dark he could see his smokes

Why not stay with me getting sick

He said yes he should of but yet said he left the room because I got sick

Why sit on the end of the bed when other seats available

He said no seats available as the sitting room cushions from the pull-out bed were on them, but their obviously was His daughter sat on the chair after being hit by her father

Why stop me hitting her

He said cause he knew I was in the wrong

Why hit daughter when she gets involved

He said nothing only I told her I was sorry

Why not stop her pulling my hair

He said he did, but he didnt his own daughter even said so

He also said

Its all in my head

I am a pyscho

He didnt touch her and he would never

I didnt see anything

He is sitting on his own downstairs the last 2 years

I always tell him to go away from me

I always say the smell of u etc

He knew I did not want to be with him the last few years

Blamed me on cheating on him with a work collegue 14 years ago

he should not have been sitting on the end of her bed and he will give up smoking

My sister has had many affairs on her boyfriend through the years even an affair with my cousins boyfriend, I telephoned her boyfriend to tell him about the incident but he said he believes my sister 100% that nothing happened, so I told him about all the other affairs she has had but he thinks I am a woman scorned and said sure why dont u throw your husband out.

I havent told my mother because 14 years ago when I was told a rumour that they were together my mother said well it would be his fault not hers, my mother knows she is a slut and stands by her so it would be pointless

I asked him would he take a lie detector test he said he doesnt believe in them. I am torn apart, I feel so alone and betrayed and dont know how to move forward, this is my 3rd week lying in bed, I asked him to leave but he says he has nowhere to go, he cant do enough running around for me but I feel I cant move on until he moves out, do I really want him to move out, totally confused

any comments welcome xx
