Emotion and physical

Not sure really where to start but here go's Married for the past 23 years with two beautiful children (21 + 19) the last two years of our marriage just seems to be dead, I have tried so hard in the past to make it kinda work, in the last year we have had sex once and it just felt very unemotional since then she's either sleeping in the spare room or in the main bed wit layer after layer on, I'm self employed I provide for the whole family in every sence of way and I feel just Used and lost mentally, I'm 53 years young I keep my self fit and strong, I've seen friends who have gone through the divorce line and it looks just very unpleasant, I'm not sure either to go down the paid services that women offer, all I would like in life is someone who appreciates and love me the way I would like, a kiss on the lip, not just a mother's peck - hor passion sex - a laugh - a side glance- all my does is be on her phone and flick through social media- sorry for the rant - I still love her in a small way, but not as much as I used to
