should I give up or keep going? need advice!!

This guy and I have been seeing each other for more than a year. Early on we have this amazing chemistry. I think about him he calls, vice versa, he has enough of the qualities I need in a partner. We've discussed the future together and he even has told me he loves me on more than one occasion. Our sex life is amazing, we have wild animal sex, to love making and everything in between. However, he caught me in a big lie and has been standoffish ever since. He's told me he never said he loved me, that he only promised me a good time and blamed it on saying those things during a black out while drinking. When I was caught, he told me I broke his heart and there's no denying the chemistry between us.
We split up for a few months but he contacted me and although our schedules are quite different, we text pretty much every day. Although we lightly touch on real life us mostly a sexting relationship as well as sex when we're together.
He's 45 never been married 2 grown kids, I'm divorced 38 with 4 kids who don't live with me.
I want to get back to the trust we had in the beginning and I know it can be a long road, I gave sent him emails discussing my feelings for him which he doesn't respond to or acknowledge either way. I discuss feelings in length and detail and what we share between us.
It's just been really slow getting back on the same track. I don't know if it will. My attempts to discuss it are ignored and I don't want to be naggy, but I don't know if it is worth holding on to.together we are passionate but I end up spending more nights than I want alone.
It gets complicated to where I'm not allowed at his house, I don't drive, he's severely injured and all though can drive mostly relies on his friends for help.
What should I do???
