…let him go.
Yes, the future is ‘vague’, but know this: let him go now and for the rest of your life, regret and constantly think about “what if?” OR go for it and live to the point where it is great.
The problem that people have is that they stop giving themselves choices.
A long time ago, I severed those choices. I regret every day. At the very least, if I had made those choices, the least I could have done was to make another choice.
Only those that have been through it all will appreciate these words.
