ok op real talk, you strike me as one of those creeper "nice guys" that pretends to want to be just friends with a girl while smothering her with gifts and praise and talking stuff about her boyfriend. you try to play it off like youre not actively trying to bribe her into loving you and breaking up with her boyfriend, but you absolutely are and she can see that.
then you try to reinforce your own denial of your intentions by making some bullstuff public announcement that you were blocked for no apparent reason. my advice to you would be to stop being an underhanded, pathetic douche that tries to steal other peoples' relationship partners and own up to your own motivations. stop lying to yourself, stop lying to us, because its painfully transparent.
