Dear Alex,
Hope you and your family are great. I know you don’t do not want to hear what I’m going to say but this looks like I won’t be able to visit you coming this summer, during mid-June as we planned because I’ll have to stay at home due to an important event.
I’m writing to ask my apology for being unable to visit you coming this summer, during mid-June as it was planned because I’ll have to stay at home due to an important event.
In fact, (Actually) one of my siblings has suddenly announced us he/she is going to get married coming this summer in mid-June, just when I made a plan to visit you in England. By the way, it is a love marriage, and the parent of mine don’t really agree with this kind of love marriage until they changed their minds two days ago. My brother didn’t waste this opportunity, and he is going to get married as soon as possible. So, I’m really sorry that I will be unable to visit you and do all those fun things which we planned. But we can reschedule/arrange our meeting and I could still visit you in August.
