So I found out my husband had been what he called "text flirting" with some women he met online. Recently we had been having really really bad problems, and on a few occasion scheduled marriage counseling but everytime he cancelled, cancelld, cancelled. So then about 2 weeks ago it got real ugly, ad the next day he came to me said he wanted to do anger management and then we could do the marriage counseling. I went to the counseling by myself and I think got real good feed back. So last nigt something told me to go throw his phone, yes it was wrong but i did, and i seen all these intimate text messages like i wish you could come give me a massage, and i miss you and i thought i seen stuff like whens our next date, and why did you want to meet so early and stuff like that but to be honest i got so mad i really didnt read anymore messages. Now hes sending me mixed messages. part of me feels he does not want to be married but  i guess im not ready to let go...

so is text flirting cheating?
