You'll probably sense from the very beginning that things just aren't quite on track between you. Something deep and important will be missing and until you're able to pinpoint it -- which won't be easy -- it'll bother both of you, perhaps to the detriment of the friendship. This subtle problem is partly related to the fact that you're sending out subtle, tense and very mixed signals.
Somehow, you'll be unable to make your buddy believe you're really into the friendship. And hey -- maybe you're not always sure you want to be mixed up in this. Their feelings toward you could change a lot, too. The only way to deal with this will be to wait and see what happens over time. You may find that your connection is strong, or you may find that you just can't make this friendship work.
