Condoms in Wallet

My daughter dad and I recently split from one another. We recently had a conversation that we would try to change for one another so we can work on things to keep our family together. He left his wallet down this morning and our 3 year old picked it up and took out his money cards and 3 condoms out .I am very upset about this. His response was I said I wouldn’t get into another relationship with another woman . How should I feel about this , should I just tell him there’s no point in trying to make things work. Once he leaves here today I no longer have the desire to save my family. I had something special for Father’s Day but I no longer want to do that either . If sleeping with other woman is more important than making things work with me then I wish you the best of luck am I wrong for this
