....walking around the park or coming over to watch a movie are in very well paid jobs so I don't really know if it is about not wanting to spend money or not having the money to spend on dates. I think it must be something do with me or my profile
Walk around the park shows they're too stingy to even pay for a coffee (or two, imagine) - they're almost being stingy/zero cost as a principle. Like - "they're not getting the price of a coffee out of me til I see if I want to see them again/shag them/whatever".
Your lack of full photo might be exacerbating that - because they might suspect you're a "figure" catfish (they're always moaning be about how heavier women using angled, contouring and filters to produce great looking face pics but beware a lack of body pics etc. But they're still wankers so ....
Come over to watch a movie sounds very much "net flix and chill" i.e. hookup/sex.
Those ones are looking for a shag and can't even be arsed hiding it.
They also have apparently zero realistic idea of how any risk averse, safety conscious woman would ever give an essentially total stranger off a dating site her address, let him into her home etc without getting to know him at least a bit first, it's bizarre. Maybe some women do it and take the risk, so they think many would. I think Jamila Jameel wrote a column on how a tinder date came to hers first meeting and had some sort of medical emergency/passed out and it was stressful trying to get this essential stranger medical help. So apparently some women do it, and presumably get away with it without being raped and murdered.
I don't think it's your profile (aside from, as I mentioned, that they might be suspecting figure/weight "cat fishing from the lack of a full length photo); I think old is chock full of men looking for hookups with as little effort and cost as human possible. And they're ruthless about it. They just go on to the next. They e got a scattergun approach and probably hit something sooner or later, so that's what they keep doing.
