I'm 55 yo and married with 2 sons in their 20s

About 7 years ago I came out as bisexual to my wife of 15 years

I had lots of experience of being with M and F partners long before we got together but she didn't know. I thought I had been clear on that but it seems I wasn't.

Huge upset then and since then we have separate rooms but still live together and love each other (well I love her! Hope she loves me....)

My sons are sorta aware of the situation and the older one caught me on a bi chat room about 6 years ago :(

So things are now very settled and we just 'live our lives' and look after each other

I am not going to cheat on my wife but the urges to be with a guy (or someone) are growing

Advice / thoughts please

Sending my love to you all.
