You are not overreacting.
If he is your exclusive boyfriend, he shouldn’t be on Tinder in the first place.
If you are both in an exclusive relationship, texting some girl that he met on Tinder isn’t a good sign of trustworthiness.
If you are both in the know and agreed to use social dating apps for fun, that may be a different story.
However, if you just found your boyfriend doing this and he never made you aware of what he was doing, there is a problem.
Being on Tinder in the first place is worrisome.
If he is in an exclusive relationship with you, he should have no reason to be on Tinder.
Perhaps you both initially met on Tinder.
Well, if that is the case, he should be done with Tinder now that his objective has been reached.
If you are both in an exclusive relationship, he should be focused on that and not on Tinder.
Perhaps you feel like he simply decided to check his account for curiosity’s sake.
Well, that really isn’t an excuse.
He has already met you and agreed to be your exclusive boyfriend.
Even if you may have met through Tinder, there is really no justifiable excuse to continue having an open account or profile on it.
The moment the both of you decided to get into an exclusive relationship, he should have cancelled his Tinder profile.
You should have done the same as well if you had a Tinder account.
In other words, the both of you should have decided at that point to cancel your Tinder accounts and focus on your exclusive relationship.
Even if you never met him on Tinder, he shouldn’t be on it as long as he is in an exclusive relationship with you.
Perhaps he has told you that he used it in the past but never takes it seriously.
Perhaps he told you this during the dating process.
You probably didn’t think too much of it because he told you that he never takes Tinder seriously.
Well, that really isn’t an excuse either.
I know that there is this general notion that Tinder is just this playful place where people can come to and do a little harmless flirting but there are genuine hook ups that occur through Tinder.
It is not the normal social media app.
People get on there with the intent of either hooking up with someone or finding a relationship.
You should understand this.
You should also understand that this incident was probably not isolated.
In other words, there is a good chance that he has either texted this girl that he met on Tinder before or he is texting other girls that he is meeting on Tinder.
This is a problem.
This would indicate that he isn’t taking the relationship that he has with you too seriously.
This means that he is more than likely keeping his options open for someone better to come along.
If you begin to have strong emotional tendencies toward your boyfriend, you may end up getting seriously hurt when he chooses to leave you for someone else he met on Tinder.
Talk to him about this and get his genuine opinion about the kind of relationship he believes he has with you.
If you are both in an exclusive relationship, texting another girl on Tinder is unacceptable.
