Hi, im from eastern Europe as well so im familiar but let me give my perspective on this topic from what i seen in my environment.
I personally dont think marrying young is a good idea. These people get consumed by smallness of the environment and get stuck there, its hard to get to any greatness when u are changing diapers or to enjoy life and travel the world, when income in this area is small enough for one let alone a family.
These kind of relationships usually sour over time and build up resentment when they realize they are full on adults now but they barely LIVED(very common theme) , did anything or experienced the world and its harder to enjoy and travel with kids. Lately i asked my brother how was his vacation and he said kind of tiresome as they have to focus on the kids, tho he married in his 30s but cant enjoy vacations as much as he used to with his wife.
They barely have time to work on themselves and they change over time as their parthners too and realize they lacked relationship maturity, they dont know themselves well enough or the kind of person they truly want and attraction falls over time from what i seen this is usually the case and fate of these relationships that start in their 20s . Also the income is hardly enough for decent life.
You bring a point of growing together its a lovely thought but hardly realistic when kids are there its all about the kids all the time.
Also higher quality women want the finished product of a man not to grow together with someone if they can do better.
Im 27 now commited to deeper healing inner growth then full on khan journey for few years likely. Now is time to build oneself for greatness, income, travel the world and experience what material world has to offer (continue my spiritual journey as well just not as main priority) and really ‘LIVE’ as they say, ideally with a good parthner because when kids come all that will take a hold.
I had some hard recon with sin of lust overcoming me so im taking more time with healing before going further khan stages but the kind of quality woman i want beside me it will take more time to build myself up or if that doesnt work out i will take some younger girl in 18-24 to travel with me and maybe family later or Leo di Caprio lifestyle if no kids.
Love to hear more on diet u are on im trying to improve always tho probably best to dm me on this as offtopic from this.
