I recently got back together with my ex boyfriend. We broke up because of our fighting and my drug problems. I went to rehab to quit drugs, because two of my relationships ended because of my drug problems. We took a break for 2 months, and got together again. Near the end of our relationship the first time I started losing trust in him because of the flirty texts he had sent to this girl at a party when he was drinking. Now, it seems I can't trust him at all. I'm always fearing when he goes to the bar he's going to do it again. I get immense amounts of jealousy even when he talks to better looking girls. I'm so afraid of him cheating, or hiding something from me. I want to trust him, because I love him so much. I overthink our relationship quite a bit, and it gives me these depressive episodes, and I feel like it's ruining our relationship. How do I learn to deal with this fears and insecurities, and learn to trust him?
