Partner is not attracted to me

I have been with my other half for 13 years we have 3 beautiful children together

We have had so many ups and downs he’s had sex with prostitues and I stupidly have stuck around I honestly know I sound pathetic but love him and I try to forgive him . He has done it a few times over the thirteen years

We have prob had sex 6 times in the last 12 years .

We have had some counselling but because of work we end up not attending

Well this morning I ask him well told him that I know he’s not attracted to me anymore and hasn’t been in a long time .

I cried it was the first time he agreed . He says it’s not a physical thing on how I look 3 kids I’m not perfect carry little extra wait so does he neither of us are huge people thou .

I told him that we are wasting our time and I love him but what’s the point

He says he loves me and wants me to give our relationship a chance . He told me to give him 6 months I can’t see it changing I’ve waited 13 years .

He has depression and had a few things happen to him he is good at distancing himself he has done it to his own family but trust me that’s a good thing lol

Please no nasty comments about should have left long time ago . I just want to talk to someone
