<human>: I am somewhat reluctant to post this, but it has been clawing at me for awhile now and I would like some advice.

So I have been married for close to four years, been with her close to 6. Since we have been together she has cheated a total of 3 times. Once since we have been married.

The last time she cheated was 2 years ago, we went to counseling, both singles and marriage.  Things seemed to be going well for awhile until recently.

My wife met a guy at her school. They quickly became close friends, she began actually hanging out with him about 2 months ago. At first it seemed fine, but then she would stay out late and tell me she lost track of time. She would stop texting me when she was out. We have a rule that we don't text members of the opposite sex past a certain time and she began breaking it for him, saying I was over reacting and not being trusting because of before.

I have a gut feeling something is off, she will leave her phone upside down when she places it down now. Little things like her showering with the door open since we have been together have changed to her closing the door. 

When I talk to her about it, she just tells me I am being insecure and makes me feel like I am being crazy and irrational. I have not even met this guy and she just keeps making excuses to why I cannot. 

I would like to mention she has always been super independent, but I am still working through trust issues, just not sure if they are unreasonable.

Can you summarize the given text in a few sentences?
<bot>: Wife has cheated before and has a new guy friend, has been acting weird and making me feel like I am being the bad guy.
