I don't think they mean anything at all except that some days H probably feels guilty and wants to be nice.
Ok, so he feels guilty and wants to be nice. Is that something you feel and attempt towards someone you hate? We tend to want it to be an all or nothing proposition (love or hate). When you stop to think about it though, hate is not the opposite of love (both are very intense emotions), indifference is. I was more afraid of indifference than anything b/c it isn't an emotion at all. Since this is what I've gotten, I don't have to be afraid anymore. A nice gesture can just be that. Someone who cares enough (whether guilt or not) to do something nice. That may be all it is. Who knows. If I had a working crystal ball (my magic 8 ball doesn't tell me anything), my financial difficulties would be over in a heartbeat. Ok, they probably wouldn't be b/c I wouldn't have the heart to charge. Sigh.
It's hard to have hope without expectations. I call it life on the razor blade (hmmm, perhaps a short story??). If you can "pretend"(remember when we were little?) he's someone your interested in, but haven't started dating and SUBTLY flirt with him. Thank him for his kindness, take an intrest and LISTEN. It might help. Can it hurt?
If you journal at all, please write down what you do and his reaction (if there is one you can see) to it. Sometimes, it's really hard to tell.
