[Ask The Ladies - Read First Post]

I need some help and for some reason, I wasn't able to make another topic about it. Anyways, me and my boyfriend have been together for 5 years on valentines day. In the first two years of our relationship, I had moved away to school and that led to him cheating on me with his ex-girlfriend, A, that he dated before me. I found out because A facebook messaged me and told me. I confronted him about it and he eventually came clean. It took a long time but I decided to forgive him to try to make it work out. Now two days ago, he was drinking with his good friends and got drunk. He ended up texting his old friends with benefits, L, that he always thought she was attractive and he wanted to bone (have sex) with her. L is in a relationship and said no. The next day, while he was driving to my house, I get a facebook message from L saying she had to tell me something about my boyfriend. Feeling uneasy, I agreed for her to call me. L told me that she had a past with my boyfriend, that they were friends with benefits 3 years ago, so around the time he was cheating on me with A, and told me what he drunk texted her. She also contacted him the next day asking if he was sober and why he would say that to her. He said that was how he felt and alcohol gave him the courage. She asked that if given the opportunity, would he be down to bone? And he replied, richard simmons yeah and said that he knows his boundaries though and wouldn't do that. When I confronted him about it, he said that he said it under the pretext knowing that it would never happen and how sorry he is. L assured me that this was the only time it happened and that they weren't messing around prior. He's been blowing up my phone with how I'm everything to him and how much he loves me and how much he knows he richard simmons up. My heart is broken and my trust with it. I don't know if I should continue on with this relationship and try to make it work knowing that he feels about someone else even though he swore on everything that he wouldn't have acted on it or just throw in the towel. Advice would be greatly appreciated, thank you.
