I don’t think that’s particularly salient. It’s not difficult to portray yourself as non romantically interested.

I’m not buying that the poster behaves in a way consistent with just looking for friendship at all. Especially with the comment that partners get suspicious.

I would struggle greatly to portray myself as non-romantically interested and still have the level of intimacy many women have with their close friends. They're real touchy and huggy. Resting heads on laps or shoulders.

My current partner regularly has sleep overs with her best friend where they rug up on the couch and watch movies late at night. They share the bed when my partner hosts. And its not exactly something strange I haven't seen before.

Physical touch is huge to me when it comes to feeling close to someone so when I think of women's more emotionally supportive and intimate relationships these are all the the things I think of. Maybe it's different for you. But I've seen lesbians express frustration at how it can be difficult to tell if someones interested because of it, with some relationship origin stories being that they were both having late night movie dates with their 'straight' friend, wishing the other was gay too.

Right because if you wanted to signal you were not romantically interested in a woman you would not do any of those things. That doesn’t bar you from having an emotionally supportive relationship.
