Fellas I need some advice. My girl who is a lot younger than this creep has been followed by a man all around the gym including sauna and pool. The man knows her and her friends age yet he still persists. He doesn’t directly make contact however he has done before but like today, he went into an empty sauna and sat directly next to the girls and was man spreading. I’m not in the gym the same time as my girl but she tells me. I don’t know what to suggest or do but i need help and suggestions. As a boyfriend and a man i want to take initiative to resolve this situation but i need advice.
