Cheating on gf with a young man, keep it to myself or tell?

[PeterDix]

I am a 49 year old man. I been in a committed relationship with a woman 10 years older for 7 years. We live together, have no kids, she has a 27 year old son. 

My gf knows I have a thing for men also, and she is fine with it. Our relationship started great, but slowly deteriorated. My sex life has been horrible for the past years. This is mainly cause we struggle financially and can't agree on many things. I don't get along with her son and she hates it. 

We stopped sex about 5 years ago, she gives me oral occasionally but that's it. I lost any want to please her gradually and miss good sex. It made me frustrated. 

Lot of times, I was really horny and desperate, so I signed up for different hookup sites. There I met a 19 year old man from nearby University. He advertised he had a kink for much older men, so I sent him a message and we ended up having sex. We been seeing each other for 4 months now. My gf is unaware. 

Since then, I lost all my attraction to my gf. The 19 year old boy is much fitter, stronger, better looking and can give me a good pounding which my gf can't. I started looking at younger women in their 30s I could potentially dare too. I think I underestimated our age gap. 

I really don't know what to do. Should I leave my gf, and say I fell out of love for a long time, and that I want to date younger, or drop the boy and stay in the relationship trying to improve it? I don't want to hurt her or get in a conflict with her. Our arguments are nasty and I don't know what she would do. 

Please give me advice.

You've got nothing good to say about your girlfriend, so just end the relationship
