Oh wow. Incredibly touchy.
No, not bitter at all. My retired parents very kindly gifted us £250, and a beautiful painting of our wedding chapel which is my most treasured possession.
I have no shame in saying here my wedding cost approx £20,000. My husband and I are fortunate enough to earn enough which meant we happily paid this, and spent 3 years saving as much as we possibly could to do so. Never once did I discuss the cost with my parents, or my PIL. Seen zero reason to, the decisions we were making were ours. Similar to any other decision we've made in our lives, it's nothing to do with anyone else.
As I said, I have zero issue with gifts such as wedding dress, or monetary gifts etc. But the idea that as soon as someone gets engaged and starts planning a wedding, people other than the bride and groom should be involved in the cost is strange to me.
I didn't ask my parents for money buying my own house either. I've been raised my incredibly kind, thoughtful parents who would give you the back of their shirt if you needed it, but I've also been raised to be independent and work for what I want. My life choices are nothing to do with anyone else. If I want something, I'll work for it and save. If I can't afford it, I won't do it.
