We all should know better. With few exceptions everyone had relationship with at least one person when could be like “what was I thinking???” Not just about relationships. About other things. Influenced by other peoples opinions, denial, don’t trust your own guts etc etc Trusting oneself is important.

The only thing we could do is to try to learn from it. So next time you meet someone who is that dependent on their mother plus had other issues, you’d not go for it.

Good you only spent a year with a wrong person. Some waste 25 years of their life. So you didn’t really waste time. Very wise
