I know that normality is a theme here, but his situation is not one that should be judged from a standpoint of what is normal, but of what is ethical.
And, assuming that most partners he "gives his love to" are not exactly aware and consenting partners in a polyamorous relationship, but rather each believe they are his girlfriend until they find out they are not; it is difficult to call his choices ethical.
His hiding in fear of being judged comes off as an excuse to justify his amoral behaviour, or as victim mentality, stressing his fear of being abnormal, rather than the pain, disappointment or betrayal his partners have doubtlessly felt in the past.
