<human>: Can you summarize the given text in a few sentences?

Hello reddit,
I'm a 19f and I think me and my 20f boyfriend are done for good? We've always been the couple to be on and off and this time just might be official but no ones officially said it.

Our fights are usually someone's mad, we don't talk for a few days, he'll either ask about our son (7 month old)or one of us come out and say we miss the other. This time we haven't talked in 3 weeks today and he's blocked my on every form of communication, changed his information and profile picture on Instagram to basically scream "single" and hasn't checked on our son.

Would closure in this situation be helpful or hurtful? And I'm meaning sit down and talk "are we done for good" type conversation? I don't want him to think I won't leave him alone but It's eating away at me and I'm not sure what to do. Thanks in advance guys!
<bot>: boyfriend of 4 years hasn't spoken to me in 3 weeks, should I just leave him alone or do we both owe eachother a last conversation.
