My wife and I have been married for just over 2 years and she is from Paraguay and here on a conditional greencard. We just had a newborn baby when I found out she has been sexting other guys but this is just the first time ive caught her. If she's done it once, she's bound to do it again right? She claims its post-partum depression but after giving it a few months, she has still been trying to do it with other guys. I'm debating to I just have her greencard pulled and divorce and get rid of her? What do i do with our newborn son. Im 32 and work as a pharmacy clerk and make pretty low income. I have family willing to take us in but its so hard to just walk away from a marriage. what do I do? Any advice would be appreciated.
