As long as His energy is intact and even enhanced from cheering you up, it's not codependent. That's more like unconditional love, the kind that's good for you :).
But if you have a need to be cheered up very frequently and depend on him to validate your self esteem, that's more like codepedency.
How does he feel when he's able to cheer you up? I bet it makes him feel good, but he has to already feel good to begin with :). And he can't abuse it, or His self esteem will come from cheering you up, if he makes it that way.
See how love is like food, or anything that feels good? It's really good for us in moderation, like anything that's healthy. But if it's abused, we can use it to medicate our issues, just like we would pain pills, lol.
Both people really have to feel good on their own, before they can not abuse Love.
One almost has to go through the experience to find out what their needs and wants are, and to be able to tell a difference between the two.
Love within ourselves and our HP's can be a need more than a want. But romantic Love for others is really more of a want than a need, although there's need qualities if we get too attached, lol.
It kinda sounds cold, but I believe that we're all perfectly capable of making it without romantic love, until we find that we really don't need it to be happy.
But once we do, and then we find romantic love, it makes it TWICE the fun, because we're okay with whatever the person is doing or the way they are.
And they'll mirror us more, so we'll be more compatible together. And there will be more harmony.
I'm really happy for you, hon :). You're a very strong, authentic person and you've done a lot of work on yourself for this relationship to come into your life :). I wish I had your energy :).
And this was just my opinion on your question :). Everybody has their own way of seeing things, and I hope others will chime in and share their thoughts :).
Hope all is well and that you're enjoying the season :)!
Hugs,
SK
