Should I give this Libra guy another chance?

Hello Libras, I'm here to ask your opinion. Me and this Libra man were in a situationship. I was in a relationship that ended with my partner dying. It was rough and I decided to take time to recover before dating someone else. I met Libra man last year. He too was recovering from a difficult relationship. We became really close and pretty much acted like a couple without the title. All our friends joked when we weren't together somewhere, like wow you're here! It means Libra must be near by! For the duration of our thing, he acted like he didn't want a relationship with me nor anyone. We always said we were healing together.

December was a rough time for him for many reasons. I helped sort his life out and he was very grateful. He told me he was always the one being there for others and wasn't used to have someone present like I was. We grew closer together.

I was practically living with him part time. Things were fun and loving. We'd often fall asleep together, saying how happy we were, how we enjoyed our situation and how much we love each other.

Until I learned about a close friend of his. They'd met in November. His son and her son were friends. They'd talked when he drop his son at her place, talked on Facebook. At the time she was dating someone but was going through a break up. Libra being the caring man he is, listened to her. They'd gotten close but only through texting and some phone calls. They were never physically together. She knows about me and was shocked to learn we weren't dating.

For a whole month they talked and flirted. I was never told about her by Libra. I know he kept it for himself knowing it would break my heart.

We had a very long talk about our relationship and he told me he didn't know what to do. He asked me if I wanted to talk to her and I said yes. We talked. She told me she knew about us but he lied about the sex part and when she learned about it, asked him to stop but he couldn't.

I told her my story and I suggested she take time to recover after her 5 years relationship before jumping in something new with my Libra because he deserved better. She didn't like that. Apparently he told her he just wanted to stay friends but they talk often.

I've been trying to reconnect with Libra but he's been distant. I later learned he was depressed by all that happened. He feels like shit for hurting me and feels like he doesn't deserve my love. He's pushing me away.

We met for a dinner date and we talked. He told me he loves me and he doesn't understand why I want to be with him even after what happened.

Wants to try again.

Should I give him another chance? I low key wanna reach out to the other girl too and ask what he's told her.
