My husband loves me

My husband loves me a lot it's been 15 years since we have been together (relation plus marriage) Last month we had a baby boy! The problem is that I caught him talking to so many Asian women just for fun on dating apps like Thai-friendly, Pina Love etc. It was not love love-dove convo. When I confronted him he admitted his mistake but he said it was just for fun. Conversations with the girls were not continuous on and off. I was angry he apologised and gave me so much assurance it won't be happening again. Then today after some days I saw he again searched Thaifriendly on Google. Now what should I do? I'm so depressed.
