Did this woman set up a blind date for my husband?

[MarbleCake33]

My husband and I have been married 10 yrs and we don't get along but we are still in marriage.

When we had arguments I know that he occasionally called his friend "A" in his hometown and
talked bad about me.

My husband visited his hometown by himself the other day, I came to know that he met his
friend "A" and his wife "B" there.
I have never seen any of them in person, I have only spoke to "A" on the phone a little bit
many years ago.

I saw my husband's facebook and found that "B" was uploading some pictures of the night
they got togehter, my husband said that it was a drinking place with a little dancing area.

It was a group of 6 members that night as follows;

A
B
A's cousin "C"
"C"s wife "D"
B's friend "E" ( single mom)
My husband

It looks very strange to me that my husband was drinking with 2 couples and a woman.
I asked my husband if he danced with "E".
He said no.

Do you think A & B set up a blind date for "E" and my husband?
Thank you all for all replies so far, I would like to add that I trust my husband and
I don't think he expected the situation.

I just want to know if his friend A or B had intention to have 3 couples in a bar.
