I am going to be completely blunt with you. If you don't change your behavior immediately, you are going to dig yourself into a hole you will not be able to get out of and it will end badly for you. You caught your wife sending completely inappropriate texts to another man and you collapse and apologize WTF??????? She forgave you WTF????
Look man I know this stuff is not easy but the first thing you need to do is find your b@lls and let her know this is completely unacceptable behavior to you. You can't control her but if you let her walk all over you I guarantee it will end badly for you.
Please read up on boundaries and start to think about whether you are ok being in an open marriage.
