I have been with my partner for just over four years now and two years ago he decided he needed a break for a few weeks. After the break we decided to stay together and have been together since, I just haven’t been able to move past the situation. I confronted him about the break and asked whether he has spoken to or dated anyone else during this time he said one, which he met at a party. I didn’t believe it so continued to poke around and confronted her, she said they met on Tinder, never in person. Confronted him, he denied it, said they met at a party and that she was lying. Continued to poke around and found another girl claiming she also met him on Tinder and even dated for a bit. Again, when confronted the story was denied and he claimed he doesn’t even know her. Bear in mind both girls were confronted off a fake account so neither knew it was me. He has sworn he was never on Tinder and never spoke to or dated anyone else… And gets so aggressive when I do ask or mention the situation, not sure whether out of guilt or actual frustration due to the fact that I can’t trust him.
What am I supposed to believe?
