It's difficult to determine someone's intentions with absolute certainty, especially without knowing the specific circumstances surrounding your relationship and breakup. People handle breakups differently, and there could be various reasons why your ex-partner hasn't asked for the house key back yet. Some possibilities include:
She may not have thought about it: After a breakup, both individuals may be dealing with a range of emotions and practical matters might not be at the forefront of their minds. It's possible that returning the key simply hasn't crossed her mind yet.
She may not see it as a priority: If the breakup was amicable or if she has already made other living arrangements, getting the house key back might not be high on her list of priorities.
She may still want to keep a connection: On the other hand, it's also plausible that she hasn't asked for the key back because she still wants to maintain some level of connection with you. It might be an indication that she's not entirely ready to sever ties completely.
She may want to avoid confrontation: Asking for the key back could lead to a conversation or interaction that she's trying to avoid, especially if the breakup was difficult or emotional.
She may plan to ask for it later: It's possible that she intends to ask for the key back eventually but is waiting for the right time or for emotions to settle.
Remember that interpreting intentions from small actions can be challenging, and it's best not to jump to conclusions based solely on one aspect. If you're curious about her intentions or would like to clarify the situation, the best approach is to have an open and honest conversation with her. This will allow both of you to express your feelings and expectations moving forward. However, keep in mind that you should also consider your own emotions and well-being during this time.
