The issue

isn’t anime, or your response

they are:

1. why this person gravitates to a particular type of content, which they find unproblematic and entertaining

2. that their response to your concerns and feelings are dismissiveness and agitation

it may be helpful to ask yourself:

1. if your most important values align.
2. if this is a typical response pattern towards you in disagreements.
3. take the above two answers into account- is this someone you want to spend a length of time with and become increasingly serious about.
4. take the above three answers into account- are you comfortable with the idea of this person being a presence in the lives of children you care about (or if it’s something you want, as the father of your child/ren)
