The End of My First Relationship

Last Friday, after meeting up with my boyfriend, I received a message from one of my net friends who  I had flirted with before. He asked me if I had time to go for a drink and get some / have some dinner later with him (no need for 'with him' , implied already) . I thought I could (past tense so not 'can') pretend nothing happened and ( keep maintain the relationshIt) carry on (continue) with my boyfriend. But the fact is I wasn't feeling it anymore so I decided to break up him. He is so nice but I'm obviously not ready to be with someone (long term relationship).

I typed (a block of word) (??) to him on wechat, and then blocked him on wechat also added his number to blacklist. 

A day later (One day pasted), while I was deleting (tried to clear) my spam messages, so that I would have more space for my new learning app, I got an English message in my inbox. appeared casually  I felt nervous about opening it but after a long time pondering, I opened the message and found there were actually three messages from my ex. I could (past tense) see he was heartbroken and could feel his despair (unnecessary/implied: through these words) he sent me. What made me feel really guilty was (tense consistency) that even though I had already broken up with him he still wanted an explanation. If the roles were reversed (If i was him and was cheated by my boyfriend), I would hate him forever and never want to see him again. The last thing he said to me was that it would be difficult to get over me. That was the last I heard from him.(Until today, I have not received his other message, and it makes me released.) I told him not to waste time thinking about me because I'm not worth it. (The most context (??) of my message I sent to him, which I ask him don’t waste time on missing or hating me because I am nothing.)

I feel a strong sense of guilt about all this because I can understand his disappointment. (Unnecessary: of never receiving my active message, and never being asked out by me.) Since I didn't feel as strongly as he did (figure out what kind of emotion I have for him), I thought it was best for us to split up (apart is the best solution to avoid hurting both him and me deeper in the future). Someone said to me ever: don't be the first one to fall in love, you'll only get hurt (In a relationship, never fall in love first ever, because that means the more it hurts you.)

Emotional story and an interesting topic, poor guy.. we call this unrequited love haha
