Gravity Drag isn ' t a thing in orbit , it applies only to ascent and descent . The Oberth Effect is somewhat related to gravity drag , but you don ' t need a high TWR to take advantage of the Oberth Effect because you can split a burn over several orbits if need be of course if an ejectioninsertion velocity is far greater than escape velocity then you can ' t split the burn much in which case a higher TWR is more beneficial <| sep |> bp gas station , birthplace gas station <| sep |> Go do some stuff around town . Miss Smith getting out and Koala getting a ton . Fuck me <| sep |> No . I ' m not saying he ' s a good guy or that his behavior is acceptable or without fault . I ' m saying I really don ' t even think that matters . Not even just the drinking whatever extent that is actually an issue in your life , I ' m not trying to pry your behavior is not conducive to having a healthy relationship with anyone . Whether he ' s the right guy or not to have that relationship with he probably isn ' t won ' t solve the problem . To be perfectly honest , my biggest issue is that , in the midst of this swirling spiral of drama that apparently surrounds this , is that you lost your job . You ' re a 31 year old adult at that stage in your life barring economic downturn or other reasons beyond one ' s personal control , this is a pretty big red flag in my personal opinion . You had a lucrative job was there some reason you could not have returned to school to pursue your passion part time ? Generally , a stable income is an important thing for an adult to have . Since your ex is not ok with your loss of income , correct me if I ' m wrong , but I ' m going to assume you aren ' t independently wealthy . I don ' t know in what other circumstances this could be perceived as normal , but for anyone trying to have a functional life , I could not say that choosing to stop being employed is usually considered acceptable . There are way too many variables and I could never know the full context and details of your life , but from what is written here , the choices you make are not conducive to a functional and happy existence . I know you want validation that your ex sucks and is part of the problem , but to me that issue is negligible . What is more significant to me is you seem to make choices that have pretty significant negative impacts on your life , and don ' t see them as being as important as they are .
