Verb conjugation of "retract" in English

Dear Maximilian, I look forward to your visit in Switzerland. After a somewhat difficult start, it seems that we have increased the website traffic and we are starting to receive more visitors.
The conjugations of verbs are the biggest problem for me. I have never studied Spanish in school, but visited evening classes instead. This year I want to take a full Spanish course.
My daughter and her husband have invited me today, it is always very nice to visit them. There were many friends there too, because it was my grandson's birthday. We were very happy and celebrating.
