Dear Lisa,
Your relationship with Chris is NOT something to give up. You have a lot of constructive energies to create a successful long-term relationship.
The only evident problem is that Chris finds it hard to search and reach within himself, and so it's also reflected on his lack of intimacy in his relationships. So what

find some good friends to compensate for the one-way intimacy challenge. On the other hand, Chris shows commitment and passion toward the relationship - qualities that are rare to be found.
