I would NEVER advise using text messages where any form of relationship is concerned. It's far too easy to misinterpret their meanings. (Texting is ideal for making and confirming routine appointments but it's a lousy way of dealing with relationships of any kind).
That thing you send texts with is called a 'phone' for a damned good reason: It makes phone calls! My advice is NOT to text your (former) friend but to to PHONE him and say that you're sorry for any ill-feeling that there may have been in the past between you. (DON'T start blaming Mr G, or anyone else for it, as that will force your friend to take sides. Simply say that you're sorry you fell out). Then say that you'd like to meet up for a drink (when the Covid rules allow, of course!).
If the guy makes it clear that he doesn't want to know you, you'll at least be in a position where you know for certain that there's no point in dwelling on the matter any further. If he agrees to meet up with you though, you stand at least a reasonable chance of reconciliation.
