<human>: I have been with my boyfriend for a little over two years, but known him superficially for most of my life. His parents died when he was young and he was taken in by his only living relative. Some of my family members also cared for him part time and that is how we met as children. 

We didn't see each other for maybe 15 years and reunited as adults (when his surviving family member passed away and he leaned on my family for support). I wanted to be support for him in a difficult time and I fell very hard in love with him. 

We live together now, have for a year, and things have become difficult. I'm wondering what to do next. In many ways, he is the best partner that I could ever imagine. He's honest, caring and a very genuine person. However, I believe he might be a little emotionally stunted from his childhood experiences. I am confident that he loves me and he is a dedicated partner, but he doesn't show it in conventional ways. He doesn't say "I love you" and isn't physically affectionate at all. Also, we do not have sex more than once every couple of months. 

I feel that I have been patient and understanding, but lately, am having difficulty with this. Discussing marriage, children, sex or affection is just frustrating for both of us. He claims he wants all of these things, as do I, but he turns away from the conversation every time. I have thought about throwing in the towel because I feel that he is either incapable or unwilling to grow and mature in this relationship. But I truly love him and the thought of him being alone in the world makes me want to cry. I also worry about being 30 and single and feel like I have some sudden time constraint placed on me. 

He has said yes to therapy but thinks 1. It is too expensive and 2. His issues are too ingrained to be fixed with a few therapy sessions (his words). Also we live in a small town and have no insurance so I'm not sure how to find someone good  and inexpensive to help. And I'm not sure if I want to expend the energy.

<bot>: Relationship is stagnating after two years. I love him but not sure if I'm willing to keep going with so little reward.
