Can I still work it out?

If you two were married several years, with several children, I'd advise you get together with the other married guys here who successfully salvaged their marriage relationships so you could receive the mentor-ship to pull it off.

However, I'm running on the assumption that you're just two singles, with absolutely no kids between each other. I see absolutely no benefit for you to try and salvage this as she's already told you her interest in you is waning. Your relationship is dead, she's just not ready to lay it to rest.

For her, you're just a stallion in her stable she occasionally rides between her looking for a new guy. She knows she has no competition for you, so she has little reason to bother. It's in both your best interests that you cut her off and move on.

My ltr is losing interest in me. She said that we should focus on ourselves for now. She said that she don't want to be in a relationship right now but we're still be in touch and still having sex. She said she'll comeback to our relationship after we get our shit together.

If she's telling you that she's losing interest in you, then it's already gone. That she's still having casual sex with you, after making such a declaration, then it's unfortunately an indicator that she's looking for her opportunity to monkey branch to another guy. As such, it's your duty to help her on her way and deny her access to your penis as you find another woman.

To that end, consider investing in a reliable ready reference you can pick up and study to better prepare yourself for engaging the opposite sex. I'd suggest that you get yourself a copy of Doc Love's "The System: The Dating Dictionary". Doc Love, also known as the late Tom Hodges, wrote a weekly advice column that's archive is mirrored on several sites and a podcast. While his media is a bit pricey, it's a solid foundation a guy can branch out from, but I would also suggest you review his advice column to decide if his view on dating and relationships is aligned with what you aspire for yourself. To save yourself a search, give this scribed link a gander to find out if his book is something you'd like to add to your library.
