Tinder in a new relationship

[Islande]

I started seeing a new partner early this year and we unexpectedly fell pregnant in April. We were both happy with the news but this is the first time for both of us.
Before we found out about the pregnancy, things had been up and down with our first big argument in March stemming from him using tinder immediately after leaving my house after a date, he said he just used it out of habit, but after this argument he said he would delete it.
I then found out today that he has still been using tinder but he said he had only been swiping out of habit again and nothing more. I asked to see the messages in that case and he got very defensive saying he didn’t want to be in a relationship with checking phones. Ideally I don’t either but I felt to reassure me I wanted to see whether there had been messages too but he couldn’t understand that.
I ultimately kicked him out because he refused to show me and wouldn’t talk about it further, I said the trust had been broken and I felt disrespected but I’m worried about doing this pregnancy and raising the child alone. Was I too harsh to kick him out as things are still quite new?

And these guys never want to wear a condom.

As harsh as this may sound, it’s spot on. Hrs not invested at all OP. No one uses dating apps out of habit. It’s a deliberate choice to see if there’s a better option out there.

Most people delete the apps once they’re in an exclusive relationship - the fact he hasn’t is the biggest red flag you could possibly see.

Do you really want to ge with someone who is already cheating emotionally?

I think given things have moved quicker than the speed of light I'd have been more surprised if things were now sailing smoothly. I think you need to give yourself some time alone to work out what you want to do going forward but above else mentally, emotionally and financially prepare to go it alone. You need to reconcile with the fact that the drama between the two of you will not be healthy for the baby regardless of any lingering attachment towards him.

I hated using Tinder. It was like people shopping. I'd be delighted if I was using dating apps to have met someone and no longer have to use them.

The fact that he's still using it after he's met someone and got them pregnant tells you that he isn't committed at all.
