Could This Be My Boyfriend Been Cheating

Recently I was just leaving my doctors appointment for replacing a new Kyleena inside of me but lately before putting this in me......I’ve be having some crazy symptoms of itching, redness and soreness in my private area for awhile. I goes to see different doctors and all they can say is that I’ve a bacterial infection.......I told myself okay and starting to take the medicine.....It seem to help the situation but doesn’t cure it because weeks later it will come right back in the same area

So I go back to see my OBGYN and do a full check up on everything that women could catch....Everything came back negative but however there was one thing my told me that I’ve contacted and that’s was “Herps” I couldn’t believe as to what I was hearing because I’ve been with my boyfriend for 7 years and yes we have had our ups and downs to the point we wasn’t speaking......But we have got back together in February of last year.......I’ve never in my life contacted anything like this.

I’ve even mentioned it to him about it and maybe go get himself check out.....A day go by and he calls me saying he doesn’t want to be in this relationship anymore......Is this a sign of guilt?..... or could it be his out here doing something and didn’t think I would know?
