initially i wasn't gonna post here since i think everyone else who posted before me already listed my sentiments, but as someone who has Been In These Specific Shoes(TM) (feeling like a consistent after thought in the rp relationships she cultivated, only exacerbated by people gaining other priorities in posts and/or flocking to other individuals instead -- seriously, if you look at my old posts here i was an emo bitch about it LOL), it's completely understandable to feel that way, and i think that a lot of people in the general rp community have these kind of feelings, at least a little deep inside. what matters is how you take it, respond to it, and what you choose to do with the time and energy you have.

end of day, rp is a social hobby, and depending on how much you pour into it, the connections, reception, and experiences you glean from it will do a lot to how you feel about it, people in the community, and even beyond. ven's got a really strong point imho: a lot of the time, what matters is finding the right circle and/or partner for you — preferably people who match your interests, beliefs, plotting style, etc. or people who are willing to work with your style, brand, or approach, hand-in-hand. it doesn't have to be a 1:1 match; it's what you and your partner are willing to compromise on, discuss, work with, and play off. me and my closest rp partner here of 7+ years don't have 1:1 exactly similar preferences and plotting approaches (heck, a lot of the time we actually have clashing ones and that usually means we have to rewire, rediscuss, or set the record straight a lot LOL), but ye, if there's a willingness to accept, cooperate, and play off each other - i think that can prove pivotal in rp interest and/or muse.

ofc it's easy to say "find the right place / partner for you" and it's rare as hell to rlly get that, me and my mine took who-knows-how-many experiences (good and bad alike) with each other to really reach where we're at now, but the trying does a lot. join multiple sites, take risks and take wanted ads, make wanted ads, reach out to people, plot outside your comfort zone, pitch ideas that are purely self-indulgent and see if someone bites, etc. etc. it's gonna be a hit-or-miss all of the time, but when things hit? it'll hit good, and that's what matters. not only will all of that help in maintaining the momentum you want / works for you, but it lets you meet more and more people. and sure, like more than half of them will be a miss (maybe even give longterm grief that leaves you jaded and bitter and having aged older than you really are), but you'll get somewhere good if you're willing to keep trying. i think a lot of people can understand and/or see that, and make their own decisions on if they want to do the same if you approach, play off each other, verbalize when concerns arise, understand, and move with that.

tl;dr compromise where you can with people, interact and be ready to speak up to make things work (if you want to make things work, that is, i'm a firm believer that healthy confrontation is such a mandatory ingredient in longterm and strong relationships, both in rp and out of it) but never settle for less than what can give you joy.
