He sounds a bit like the boyfriend I broke up with when I was 19. Complete love bombing.
Would complain when I went out with friends so I started only going out with him. Tried to break up with him but he cried so agreed to give it another chance. Went fine for a while, then he started to tell me I was too opinionated if I disagreed with him, started turning up at my door on weekend nights when we hadn’t arranged to see each other (and he had driven 3 hours as we lived 180 miles apart).
During sex, I realised he’d taken the condom off. I went on the pill and he told me it made me very moody so I agreed to come off it. Shortly after, a condom mysteriously split, and he tried to put me off getting the morning after pill. I did anyway. He sulked.
I tried breaking up with him for a final time. He rang my dad to say I was behaving strangely, and he was worried about me 
Luckily, my dad told him to fuck off.
Ex rang me a while later to say he was suicidal without me and would do something stupid if he couldn’t speak to me. I blocked him.
He had a new girlfriend a week later, and she was pregnant within 3 months.
