Melis, the subject I'm going to write to you about is a very important one. The house your Cherkes grandmother lived in in the past was in Istanbul. Investigating (studying) the history of 100 year old houses, (they) are very important and valuable. I talked to my lawyer friends, it's possible Melis, other people are winning this kind of lawsuits easily, other people are winning as inheritors. I'm following the news on TV, you can do it too, believe me these kind of lawsuits are won easily, you can sue in Istanbul, if you want talk to your family, these lawsuits are being won by law court decisions, I have researched this issue, I would like to help you, old houses in Istanbul are very expensive... newspapers always write about this kind of lawsuits. Melis you can do it too, write a message to me.

PART 45

When I got in, I saw that almost all of the Manas University academic staff were there. Some came with their spouses; and the single ones were spreaded among the tables in groups. I greeted the ones I knew, passed by them and joined my single friends that were seated by one of the most strategic tables in the room. They were the permanent teaching staff employees of different faculties of Manas University.
Serkan was an engineer. Even though he didn't have an academic background, he was brought as an assistant dean to the Engineering Department. Even though he was young, he became quite an expert on the subject of protecting his own interests. He would try to impress young girls with his tallness, his good clothes and his sports Mercedes car; but because of the dryness of his inner world, he couldn't manage to establish a long term relationships with any of the girls he went out with. The strong and experienced character image he tried to dress upon a week personality, looked as a too large outfit on him. Lately I've been feeling rather bothered with his show-off manners and began to put a distance between us.

I'm in Istanbul. Someone is telling lies about me. Do you believe me or him, xxxx is doing that to make me give up on you. But let's neither you nor me do what he says. I and you love each other. Don't call xxxx and xxxx. A big problem. I'm waiting for you in April 5th. Don't ever answer xxxx's calls. I'm serious with you. Don't do anything anyone tells you. If you do what they say there would be a big problem.

"yaklaşık" means "approximately".
I can translate the sentence but I'll leave the explanation to the experts:

Since the school vacation had started it's been approximately one month.

May the hands which hung you be broken. Friends of the sea.

(I just translated literally, don't know what it means)
