hey
I've got a guy friend issue as well, and i can sort of connect
First of all, is this guy really in love with you? or does he just claim to be? Being in love doesn't make one say hurtful things. Maybe he just likes something very special about you and thinks that to be love. also, sometimes boys say hurtful things, just to check whether you like them back. if he told you that he shouldn't have met you at all, maybe he wants you to say something like 'no ! i don't know how i would live without you!' or something like that. I'm not sure :P Boys can get like that though.
And about that second part, i guess he was pissed with you for not talking about your bad day with him maybe because he imagined you were close enough to tell him about it too. I would suggest keeping a little distance from him for a few weeks. what i mean is, dont keep talking to him about these little things every single day. in fact, don't mention them at all. if he is ignoring you, then he's expecting you to follow him around like a puppy. puppies are cute, but i doubt you would be so cute if you did that. say hi, how was your day. bring up nice topics and talk about good things. it will help you a lot, as well as your relationship. and, i would recommend the book You Can Heal Your Life by Louise L. Hay. She is an amazing person who has written an amazing book
Lots of love <3
