Hi everyone, I am a 26years old female, a working class and I need your advice

Hi everyone, I am a 26years old female, a working class and I need your advice. I started a relationship with a guy few months ago. We were friends before we started going out and during that period I was dating someone else. I fell in love with him, and I had to break up with my former boyfriend. About 2months into the relationship, his behavior towards me started changing. We almost never see each other and anytime I ask him if I should come over, he gives me excuses about work and other stuff. Most time I beg him for weeks before we could see it was like booking appointments to see him. But he has never called me to say he wants see me. I was also the one doing all the calling, always checking up on him. Anytime we fight over or relationship, I am always the one coming back to beg even when he is at fault. We had a very little disagreement recently, he has been ignoring my calls, I sent him whatsapp message he reads but does not respond. I got angry, so I texted him, via whatsapp because he was not picking my calls that I was no longer interested and that I was tired; he also read that and has not responded.  He tells me he loves me but he is busy with work. I am also busy with work but I find time to care. I really love him and I don’t want to lose him but I feel he does not love me enough, he does not respect me and he his  taking me for granted. Should I apologize to him for what I said, or should I move on….. Please I need help.
