Is it normal that he is behaving this way?

Ok,So here it is(It might be a bit long please bear with it :))...I met this guy online on a chat site not exactly the place to find a boyfriend and I wasn't even looking for one. So i was talking to him and he seemed so sweet he is from other country and I am from other.We shared our chatting ids and off we went chatting and one the first day itself we talked for like 7-8 hours but I went with the flow and then the next day again we were chatting and that he told me that he liked me so much and was so attracted to me when he saw me on cam and my pics (same goes for him too he is pretty cute) and that he had some feelings for me and wants me to be his gf and i agreed to it (i know i m dumb) the next day he said he was ill and sick and had to go to hospital so i waited for like one day,two day etc.. but then i thought he was just playing with my feelings so i thought to just forget him and thought he would never come online but then after a week he was online saying that his treatment was of few more days but he chose to come back to home so that he could chat with me and that he thought that i would kill myself if he didnt (he knows i m suicidal lol and now u know it too).That was so sweet of him and i fell in love with him.We talked for like 8-9 hours daily (esp. the fact was it was his night when its day for me so he gave up his sleep so that he could talk to me) and yea then he said after a week he is coming to my country in my city near to my home to stay there just to meet me and said that he would stay here for a year atleast just to be with me..I even told him that i might not be able to meet him quite often but he said "u r worth the risk"...one day we were chatting and he went offline without a bye abruptly so i called him rude and went offline and then when i came online after few minutes he said "dont you ever call me rude when i am helping someone it wouldnt have killed u if u waited for an hour or something we r done bye" and then he blocked me and then i was so sad (dont ask me abt it) but then after 2 days i was again on the same site n i met him there again and he said he was so sorry and he didnt knew how to unblock me he was trying it but couldnt unblock me so yea we were together again we then spent alot of time together he used to get cranky at me sometimes he told me thats cos when he didnt get enuff sleep he would behave like this he even apologised for it and said that he felt very guilty when he is cranky to me so whenever i felt so hurt when he was cranky at me I didnt tell him cos he was a depressed person too and tbh he made me feel really nice and safe and like my previous bfs never did but yes he gets cranky on me whenever he is sick (he stays sick alot idk why )sometimes.Like on friday he said he was having blood in his pee n had to go to hopsital so i was like "ok" and then i asked him if he could be online on saturday but he wasnt online on sat. so i asked him if he could be online on sun. and i kinda forgot abt it he did message me that he was there at my 11 am and i checked it at 3 pm and he was offline so i went to the chat site and found him there and i was jealous to find him there but then it was alright as i reassured myself that he loves only me n i shouldnt be jealous even if he is talkin to some girl so i asked him how he was and he said he was in hospital and had bad blood infection but had asked his dad to get him his laptop so that we can atleast chat and i asked him if he could be online on his monday he said he would be and even came online but he was at his cranky mode i guess i was really sad atm cos of some family issues and i told him abt it and he was like "u say one more negative thing and i m going offline" (i really did say alot of negative things) and then i tried to talk to him but it was like he didnt want to talk to me so u know aftter 1 and hal f hour i myself told him to go n sleep and he said he would be online day after tom. i asked him y not tom. so he said he is not feeling good and then i said u can try tom. right/ he said ok and even wrote "i love u" in the end but i m sad atm cos idk if he really loves me or not
