Seems like there's a bunch of "friends of sisters" or your Dad - so maybe that's got something to do with how things result? As for online - I'm no expert - but this is something that I personally probably would not pursue. Those of an older age - this might be a factor in their perception of the extent to which they do or do not wish to get involved with someone younger. The rock climbing - perhaps they are mostly interested in the rock climbing rather than pursuit of any long-term involvement? When going to an activity, perhaps people are maintaining a safe distance from others (not just you) - in order for them to focus on the activity without feeling trapped in someone else's relationship pursuits. Maybe there's an art therapist who could help with some individual work and then some group work towards understanding and navigating groups, in terms of various wants and expectations. For eg., if I was going to a group, then I would not want to be made to feel that I have obligation to provide any other group member with a level of interaction that I am not ready for. Friendships and close relationships probably have to have some mutuality (or reciprocity) without impositions. This is the intricacy of human relationships - which level of relationship does each person want, or feel ready for, etc. So - my suggestion is to try some other activities, or groups.
