When you're close to catching someone cheating, that person is more likely to throw a tantrum. It's tough to be in this situation with a partner.
You were okay with being with him when his ex's name was on the front door? Just wondering, that's all.
What kind of reaction from him are you expecting if you question him about a relationship he is in now, when you aren't together with him UnforgivenII? Just wondering again.

I think there's a lot of tantrums from your examples. Tantrums are hard to receive. It was one of the major reasons why I ended things with my ex.
