Life’s way of giving us a message

Just want to let my emotions out someway instead of just bottling them up. I was dating someone for over a year, we never argued or had a fight but because of his job we only got to see each on average once every two months. He would frequently work 12 hour shifts and had to travel a lot so we rarely talked or texted when he had to do those things. When we did have dates he’d try to always make it up to me. I’m a patient person, and I’ve always have been and he acknowledged my patience countless times. But there were times he’d go days without even sending a single text so of course I’d worry and/or assume he’s working and got too tired to respond. And so I’d wait for him, there was a time back in august where I explained to him how I felt about this and how I’d just appreciate some kind of “heads up” or something when he disappeared because of his job. He told me that he would work on that and be better at communicating with me. Flash forward to the beginning of September I get a text from him saying that “we need to talk.” So of course I felt like I got punched in the stomach because most times when someone says that they want to end the relationship, I wasn’t sure why he said that because I was the kind of girlfriend who baked him desserts and offered to cook for him, always wanted to pay for myself when we went out on dates, listened to him vent, was a shoulder for him to cry on, supported and cheered his every effort, and etc. He told me that his mom thinks I’m the best woman for him. We were supposed to meet each other’s parents soon actually. But when I asked him what it was that we needed to talk about, he never responded. My patience was dominant in terms of making a decision, so I waited for him to respond. But he never did, Ive been waiting an entire month so far and he’s never reached out. I tried calling and texting a million times just to get a voicemail and a unread message. So here am I wondering what I possibly did “wrong” for him to do this. The strange thing is despite what’s going on, I can’t bring myself to cry. Like my body refuses to despite being reminded of the memories of us. I’m not sure if it’s because I’m still in denial or the fact that I know I did nothing “wrong.” But still I’d like to get these feelings out somehow. I’d like to know how to successfully move on and forget about him. I’ve already deleted pictures of us and his number. Ultimately I think this is life’s way of telling me that my patience is being wasted on the wrong person and how I deserve better. But my fear is, what if I eventually run out of patience quicker for the next person I meet due to the fear of wasted time because of my ex-boyfriend? I’m afraid I’ll ruin something in the future that has potential.
