>>2 I like what you said, wise words.
And for
>>1I really reconize myself in what you're writing, even though I'm a guy. One problem I've as a guy (I'm 18 but it shouldn't matter) is too keep a relation secret, in my country parents doesn't forbid relationships, but my girlfriend wanted to keep it secret incase it turned out bad, it causes a feeling of a prison for a guy.
You did not force this on him so you're not the one at fault, but it decreases the "love-feeling" with a feeling of not being free. At the same time, he cannot show his feelings towards you (maybe couldn't would be a better word) which is also hard, I'm quite sure you can reconize yourself a bit at the least.
ANY guy should be jealous tbh, I don't know a single person who is not. If he asked/forced you too be his friend I can only figure out two reasons for it that are likely:
1. He still have feelings for you and therefore needs you
2. Cause he doesn't want too turn out really bad.
Did you talk to him about all this? Communication is more important than anyone understands I think, if you did not talk before you brooke up, it's normal for the one getting dumped to be sad/mad/ignore the other partner a bit. He might try to make you jealous as well.
Guys are not mind-readers, we're abit after sometimes and we do not try to read everything, specifically if it's about a painful thing.
Childish doesn't for guarantee that he is inmature, even if they often goes hand in hand.
My only advice for you is too speak to him and hear him out, listen, don't interupt him and see what it leads too. He might need sometime to think about it as well.
Sorry for really long answer, I just wanted to help >.>1 your english is totally fine, I wish I could say the same about mine though.
