I've been in a relationship with my boyfriend for 5 years and find that he's getting colder and colder to me, and if I feel that way, something might be wrong with each other.

A good love, will not lose its temperature because of the change of time, a person's attitude is very important, if the person's attitude changes, it is likely that a third party has appeared between you.
<h1 class="pgc-h-arrow-right" data-track="4" >1, five years in love, he changed, he didn't love me as much as before</h1>
I was in a relationship with my boyfriend for 5 years and I found that he had changed, he was getting colder and colder to me and I felt like he didn't love me as much as he used to.
It's not that I'm overly sensitive, it's that the facts are in front of me, he doesn't care about me as much as he used to, he doesn't respond to my messages immediately, he even forgets my birthday, he doesn't care about my life situation.
My feelings for him have always been the same, never changed, I have always cared about him, I have always been thinking about him, but his feelings for me have changed, which shows that he does not love me as much as before, maybe he does not love me anymore.
<h1 class="pgc-h-arrow-right" data-track="10" >2, a person's attitude towards another person has changed, indicating that he may be empathetic</h1>
My boyfriend and I have been in a relationship for 5 years, and it turns out that he cares about me very much, and I often feel very warm because of his love for me.
Nowadays, the boyfriend has changed his attitude towards me, he is becoming more and more cold to me, and if I don't look for him, if I don't message him, he simply ignores me.
I don't know why he became like this. It wasn't until later that I figured out that there must have been another girl by his side, and he gave all his concern to this girl, so he became more and more cold to me.
The change in a person's attitude towards another person indicates that he may be empathetic and not in love, which means that he has another girl by his side.
<h1 class="pgc-h-arrow-right" data-track="16" > conclusion</h1>
Two people have been in love for 5 years, familiar with each other, it is impossible to change their attitude casually, unless they are not in love, so the boyfriend's attitude is very clear, just a layer of window paper.
If you encounter this situation, you must make plans in your heart, find each other to make it clear, and if you don't love each other, let go of each other.
