There is a saying my mother always said.
"Words mean nothing only actions do"
Its why she never believed in saying 'I love you' or anything like that. Because eventually words can become empty and meaningless, and that's dangerous especially when they are to the person who is speaking them.

I'm in no place to judge your bf because I don't know him outside of what you're telling me but do yourself a favor and make sure you can find enough of his actions that back up the words before you begin believing them.
