Am I overthinking ?

Hi ladies

So my boyfriend can go a whole day sometimes a couple of days without texting even when i tell him that i want to hear his voice he tells me that he’s busy and never calls back we’re in a long distance relationship tho, so i blocked him because I deserve soooo much better than this he’s literally the first thing i think about when i wake up and the last thing i think about before i go to sleep and obviously all the time between and apparently its not the same for him so I decided to block his number he texted me on instagram an hour after I blocked him apologizing and saying that he knows it his fault bla bla bla I forgave him but guess what? He hasn’t changed + i found out that he’s following a girl and she follow him back her account is private and she have like 50 followers only so am I overthinking or am I right?
