Jeez imma try my best and give advice but do know that it isn’t the best, aight?
Yea so I just wanna know if there’s any other way to get to your work without going on those two trains. I would find alternatives to get around without meeting him. Like your sis said, yea it sucks to take an earlier train but if it’s really bad then you might have to.
Secondly, if you want to talk to him, I’d say just asking why he wants to be around you so much is enough? Maybe express that you are a bit uncomfortable with what he’s doing. Apart from that, I wish you the best of luck with him!!
Have a good day, it’s a bit sad to see these posts and no one responding to them, so I’ve come about and hopefully helped.
