Hi, what does it means?

"selamunaleykum nasılsın inşaallah iyisindir bu yaz geleceyim ziyaretine inşaallah bir aksilik keder olmazsa sende gelemedin istanbula hayırlısı olsun 1 ay önce sana messencırda mail yazdı hotmail adresine zannedersem okumadın sen onu müsait bir hafta sonu mailleşelim parti işleri nasıl gidiyor ticaret nasıl gidiyor ben belkide sana yanlışmı yaptım bilmiyorum yalnız bırakarak ama herzaman kalbim seninle çünki benim zahoda kardeşim var oda sensin mesencırda olunca görüşelim selamlar FİEMANALLAH serserimin serçaun"

It is something like

Hi, how are you? I hope it is everything good and this summer I hope you come for a visit... then he is telling to send emails to the hotmail address?

Selamun Aleykum, i hope you are fine, i will come to visit you this summer if everything goes fine, you also were not be able to come to İstanbul, anyways , best of luck, he/she wrote a mail from messenger to your hotmail acoount, i guess you did not read, lets write mails to eachother on one available weekend, hows party works and trading going? I do not know that maybe i did wrong to you by leaving you alone but my heart is always with you because i have a brother/sister in zaho and he/she is you, lets meet when you are online on messenger, greetings.
