Friends in Rotterdam

Hi, I am an expat woman in Rotterdam. I am 35 and moved here 2 years ago. I am a single mom of 4 years old son.
I like to discover this country. I visit any place/city every weekend. But thats so boring to do that alone. So I am looking for a company that share my spare times for eating /drinking /visiting/ festivals or any activities. I like to hang out on evenings at pubs or clubs for listening live music.
By the way I like to reading and watching good series on Netflix.
Who wants to join me?
*ps: my Dutch is not good so just in English. But I try to improve my Dutch, going to the course.
Sincerely Mrs.S ?
