Questions: Break Up & Divorce

So first off me and my ex boyfriend have been together for more than 1 year He was the most affectionate and caring guy I've ever been with and was so loyal to me but i still didn't trust him 100% (due to my past relationships) So 2 weeks ago, we had an argument over the phone and its about my trust issues and I kept accusing him of cheating and wanting other girls and then he got fed up with me and broke it off over the phone Then he immediately blocked me on facebook and instagram and deleted all our pictures on his facebook and instagram We didn't have contact ever since I never reached out, he never reached out within these 2 weeks Until tonight He called me. This was our conversation: Me - hello? Him - hey... Me - *quiet* Him - u there? Me - yeah Him - are u home? If you're not, im sorry if im disturbing u Me - yeah im home. Whats up? Him - oh.. i just wanted to know if you're free sometime this week? I wanna talk to you Me - umm... Him - are u free anytime this week? Me - *quiet coz im confused* Him - hello? Me - yea im free this friday? Him - oh okay.. yeah can u do lunch on friday? Me - um okay Him - yeah coz i have day off work on Friday Me - yeah same Him - okay. What time u wanna meet? Me - around 2pm? Him - yeah okay. I will message u then yeah Me - okay Him - alright see u then. Bye Then we hung up What the f? What does he want? I do still care and love him but I don't know im in shock and confused! Why does he want to go for lunch? And want to talk to me? Coz he felt guilty for breaking up over the phone and wants to break up in person? Or coz he wants to go back together? What do u guys think?

Have you forgiven a cheater? Or would you?
Why or why not?

Me and my ex boyfriend broke up over a week ago
I have trust issues and get jealous easily so we had a fight coz i accused him of something and then he just broke it off and blocked me on everything straight away
We had been fighting a lot because of my trust issues
He has never cheated on me before and he is loyal guy but my trust issues got the best of me
This is both our longest relationships
We have been together for more than 1 year
He invested so much time, energy and money on me... but he can just cut me off like that?
Im the only girl out of his exes that met his parents and close co workers
And he's the only guy out of all my exes that met my parents
We planned to go trip together for next valentines day but since we broke up, its not happening 😔
But anyway, my friend has him on instagram and she told me that he has been posting pictures of himself every single day now and all his captions are all related to "pain" recently
E. g. "i have been in pain my whole life but now its gonna make me stronger" bla bla..
Does this mean he's in pain (maybe from breakup)? Or just looking for attention?
Coz when we were still together, when he post pictures of himself, he never mentions "pain" or captions like that and he doesn't post pictures everyday. Maybe every 2 or 3 days :/
