I don't love him anymore

My SO and I have been together for 4 years. Everything was going to well and then all of a sudden the road got very bumpy. He used to love making me jealous, he even sent me pictures of a girl he had on Facebook and told me she looked better than me and that he would try to get her (this was in 2015). I ended up forgiving him, don't even know how :/

Well the years passed, our love grew stronger, we took many vacations, 2 trips to the Dominican Republic, had the best time of our lives! And then I unexpectedly got pregnant. He was very supportive, never let me down on anything. The baby was born, we were so complete. I became such a happy mother, and then BOOM ! Things got bad again. We barely speak. It's like he's here but then again he's not here anymore. I just feel like we can't be together. I've been dying to meet other guys and give myself another chance of feeling alive again in all the ways but I'm so scared. I feel like I just don't love him anymore, he distanced himself from me and things changed entirely. 💔

Would love to hear what you think about this
