Don't drop hints. In any arena. Say specifically what you're after. Be clear.
Some ppl are not "falling back" or "ignoring" you. They are trying to deal with real life issues that perhaps you can't/won't help with.
When you have ppl who encourage you consistently like you do others? Rare and priceless. Don't take them for granted.
And if you don't have anyone that encourages you and inspires you then you need to reevaluate the different relationships in your life.
