Let's break it down. Since you forgot to tell me the most important fact, if you are in a relationship with him or not, I'll have to give you two translations.
If you are in a relationship:
I'm content with my life right now,
I'm not hurting here, just slightly bored with you.
I like you and I care about you
It's nothing to do with you. You are cool and decent company.
There are issues on both ends
I am getting restless with the rut we have fallen into, but don't know how to talk to you about it.
If you are not in a relationship:
I'm content with my life right now,
Exactly what it says.
I like you and I care about you
I just don't fancy you as a partner, for either sex or romance.
There are issues on both ends
Leave me alone.
yep..., that sums it up.
If you are in a relationship, that sounds like a prelude to "Sorry. I'm breaking up with you." If you are not, yeah. Like MM said.
