I know very little about Egyptian culture, but I think a lot has to do with what kind of feel you get from him. It sounds like his lateness is pretty consistent, and barring any misunderstandings about time zones this sounds pretty inconsiderate to me, but what you know about him may dictate different reasons. Does he talk about these female chat mates a lot, and if so does it seem like they're "more than friends"? Has he made it clear to you that he wants a serious, dedicated relationship? Has he specified that the other chat mates are only platonic friends? I met my husband online, and each of us gets along much better with the opposite sex so we each had quite a few people we talked to, and while we were apart we were both pretty insecure about this. However, time and consistency finally waylaid my fears, as it did his, and eventually the relationship became in-person and we ended up marrying. Insecurity is a natural thing, whether there are grounds for it or not, but it is an excellent indicator when there might be situations that we should look closer at and really decide what our feelings are on them.
