Am I reading too much into this, is he cheating?

CONFUSEDANDHURTING - Apr 13 2018 at 06:25
I was checking my husbands emails, and came across one that had parts missing. I went to the trash file, senses on high alert, and found the missing emails.
I am devastated. Lost. Confused.
What does this seem like? Have I got it wrong?

Someone tell me am I reading too much into this? I don't know what to do :'(
Hi,
Umm, wow. I felt a pain in my chest just reading that. You're definitely not reading too much into it. You must be feeling devastated. The only thing I can say is.......keep quiet about what you know, if you can. You have 6 days until the 19th, try to use this time to process your feelings. Meantime, you need to change plans at the very last second and make sure he can't be at that train station to meet that woman and don't give him a second alone to call her and warn her, make him mind the kids while you go on an 'errand'. You go meet her instead, and fire a rocket up her rear. (6)
Oh my!! I am heartbroken for you! And you have reaso to be concerned!
You need to find someone to help you through this terrible time in your life. But, don’t tell too many people if you want to save your marriage?
Will you be save talking to your husband about this?
Please let me know if you need to someone to walk with you and get out your emotions in a healthy way!
Use your emotions to fight for what is yours. But, in a loving way if you want to repair your marriage.
