It's so painful to see you're very worried.
People's feelings and thoughts don't turn out the way they think. That's why suffering is born.
Taking care of people is very important. However, feeling important means that making it possible for the other person to obtain the happiness they desire is something that is really important, and it is also charity that does not ask for anything in return.
If the other party wants to take care of the child, it means that they want to prioritize not having a hard time for the child.
For children, the birth parents are very important and irreplaceable.
There are many people getting divorced recently, but if there is no DV or neglect, divorce can create deep scars and shadows in children's lives.
Since children are the crystallization of parents' love, I think it's not uncommon for feelings of self-denial, such as being denied one's existence, to accompany them quite a bit in life.
You know that, and as a parent, would you want your cute child to feel that?
Of course, if children are cute, it can be said that having an affair is too short circuit, and I also think efforts will be made to repair it even if the marital relationship cools down. The couple's relationship has cooled down, but how is it for people to run into an affair because their children are cute?
Maybe they're taking things with you as just playing, and there's also a possibility that they're using children as mere excuses.
... I don't understand men's periods, so I won't say more.
Either way, it seems to me that my current affair partner is definitely not a good relationship.
First, try to really love yourself.
Look at yourself honestly and with clear eyes, not selfishness.
Are you going to continue to stain and hurt your soul after being aware of the misfortunes of an unstable person who is swayed by momentary emotions and refuses to be together because of children while having an affair?
It may be painful, but I think it's a good idea to break up with your affair partner and make a fresh start.
I think it's good to be misled by a foolish relationship and try to miss out on a new wonderful relationship.
