This is a reflection of a different issue that is bothering him.

You haven’t been as affectionate towards him as you once were.

Although he got upset over you not taking a shower with him, his anger was a reflection of his unhappiness that you have been pulling away from him.

Instead of coming right out and telling you that he isn’t happy about how you have been pulling away from him, he gets upset over you not taking a shower with him.

Guys aren’t comfortable expressing their feelings.

Oftentimes, they express it indirectly.

In this case, he got upset over you not taking a shower with him.

This is how he expresses that he isn’t happy with how aloof you have been with him.

Look back on how you have been behaving.

Sometimes, a girlfriend isn’t aware that she hasn’t been as affectionate.

It happens when a relationship is taken for granted.

The little things you would do in the beginning to show your boyfriend you care about him take a backseat.

You fall into the monotony of a relationship, no longer as enthused to do what you used to do to show your boyfriend affection.

Have you stopped or drastically reduced the amount of attention and affection you used to show him?

It sneaks up on you.

You don’t realize that you have been neglecting his love language, as you get so comfortable in a relationship, making yourself believe that those little gestures don’t matter as much.

They do.

If you have stopped or drastically reduced the attention or affection you would show your boyfriend in the past, he is demonstrating that he isn’t happy about that when he gets upset at you at mundane stuff, such as you not taking a shower with him.

Has there also been a lack of sexual intimacy in your relationship?

With a reduction of sex in a relationship, a boyfriend is bound to get upset.

Again, being that he isn’t one to express his feelings directly, he expresses this unhappiness by getting upset about you not taking a shower with him.

The reduction in intimacy is telling him that you aren’t finding him as attractive or desirable as you once did.

Keeping yourself from getting physically close to him in the shower, is your way of avoiding moments with him that open the door to physical intimacy.

His anger is a reflection of that.

That is how he reads it.

Are you at a place where you have taken the relationship for granted?

This may not be all of your doing.

Your boyfriend may have also dropped the ball in the relationship, in becoming complacent.

Sometimes, when a girlfriend pulls away with her loving gestures or with intimacy, it is not only a reflection of her taking the relationship for granted but also a reflection of her not getting her own needs met in a relationship.

This is where having a candid conversation with each other must be had.

You two probably haven’t talked about your needs in a while.

Talk about them.

Find out whether you two have been neglecting each other’s needs, thereby ignoring your love languages.

Where there has been mutual neglect, address it and fix it, so that you two get back on the same page and infuse energy back into your relationship.
