Love your partner, he loves you back. Any small thing is shared with him first. Get the same treatment from him. There is no mistake anywhere, but the tune seems to be cutting these days. The other person is asking for space, as if for some reason it is uncomfortable to be with you for a long time. It is not that he can be labeled as a ‘red flag’ at all. Where is the problem though? Both of them are not involved in ‘enmeshment’ (enmeshment)?
In order to know, you must first understand what Enmeshment is about love! A relationship where there is no so-called distance between two people. And not voluntarily. Both are guides in each other’s lives. From ‘how you’d like to dress’, to any big decision in life, they are by each other’s side effortlessly. Neither of them think that they should hide anything from the other. No problem so far, but the other ten couples might be a little jealous of you. The problem is, there are huge downsides to such relationships.

what to do
No matter how well we understand each other, such problems are usually not solved by talking. If you understand that complications are increasing, consult a psychiatrist. Arrange for couples counseling if needed. No matter what the defilement, he came close once with love, that should not be forgotten.
