The pull of emotions is very strong for many people, but even those with the most investment might understand it is time to end a relationship that will never work out for either person. A mutual parting of ways is the best scenario for ending any relationship where emotions are concerned, but it can still be difficult for both partners. They might have more than just their feelings invested, so the separation could even take more time than they want to invest.
Financial obligations are a part of many romantic relationships, and separating them can be difficult. If the couple has bought a vehicle, they will need to decide who gets it. A house would hold the same strings for both of them, and making a decision about it could be difficult. Large items are generally financed, so the couple might decide who will get what based on income. It could seem a fair way to do it, but it is not necessarily pleasant.
Splitting up mementos is another area where a couple choosing to end their relationship could run into feelings they are trying to avoid. The items could carry a different set of memories for each person, but the emotional ties could be overwhelming for either of them. Choosing who gets what might be difficult, but it could also be a relief if one of them wants to leave behind as many memories as possible.
It could appear easier when both people realize their relationship will never work to decide on a mutual parting, but the work involved in separating their lives will not always be easy. They will have to deal with whatever emotions and memories remain before they can move forward with their own lives. For those who do this successfully, remaining friends in the future might just be possible.
