A relationship is formed between two people who are attracted to each other in a romantic way. The key word here is 'attracted'. This attraction might be emotional or physical but an attraction nevertheless. Over time, other feelings such as loyalty and commitment develop (or not), but the first thing is always attraction.
Now, what attracts us to the other person? What makes us think that what we have is genuine? It all depends upon our preference and since you're reading this, your preference is toxic. Honestly, you don't need to worry, about your partner maybe you kinda do but about yourself, you need not worry at all. You aren't alone in your preference, a lot of people have the exact same preference as you do.
The problem is that no one really knows why they keep going back to someone whom they're absolutely certain will break them. You may try to explain it to people who oppose the relationship, but they never really get it. These might be some reasons why:
1- You can relate to them:
Well, you might be considerably more "stable" but there's just something about your partner that makes you see yourself in them. You think that they understand you and that you know exactly how they're feeling.
I hate to break this to you, but you can't relate to them. You can't fully understand their problems nor can they fully understand yours. Different factors are in play for each of you. In no way am I saying that you should get out of the relationship and leave them alone with their problems. However, you need to realise that when a person has problems, they aren't in a state to form a relationship. You need to give them care but it shouldn't be as in a relationship.
A relationship requires mutual efforts but your partner needs to be in a state where until and unless they can deal with what they're going through with your help. *Continue reading on next page*
