Rarely any online game is relaxing, it may bring fun, it may bring entertainment or relaxation, but the fact you are in a pit with other people that you do not know can drastically turn what you are seeking into something negative. Hell, I loved to play LoL and Overwatch, buuuuut I was not having fun when LoL is a team based game where your teammates ruin your fun and Overwatch crying over some Meta in a quick match game.
People that love a game and are true to a game will overcome the hardships to enjoy what they do in the game, my case is to simply run an industry business, the other alts just do a few missions or explore while the industry main goes out and mine while waiting. What I like about it is that any given time I could be hauling some goods and then they are all gone cause someone wants them gone lol.
But I find my fun and relaxation in single player games most of the time (unless I am with friends in online games for the fun part), you got no one to interrupt you, no competitive nature, no worries about graphics (unless you prefer graphics over gameplay), every thing at your own pace.
One thing that keeps me going in EvE is the fact things take long and are not handed to you so easily, which is what I dislike about other games that just hand you stuff rather than working for it. Another point that keeps me in is, like mentioned before, I can easily loose stuff, but its ok because when I play management games or survival games I find myself often resetting to do a fresh new start and grants me that determination of filling up my hangar and wallet again.
But of course, EvE itself is more like a part time job, where if you do not pvp often you end up doing a part time job that does not pay you (Well, you save up by buying plex with ingame currency but you know what I mean…) so it is only natural that if you have a busy schedule you basically do not want to watch spreadsheets pop in front of you. Not to mention that in order to enjoy EvE you also need to take in consideration what I have and accept it, that anything can blow up in seconds.
I do hope you had a nice experience tho, being around for that long means there was at least Something that kept you coming back.
