He dumped me three times in the past month with lame half assed excuses like "stress of exams" and "something in the relationship isn't right". I took him back twice but now he wants me back again a third time. He messaged me saying the real reason he has kept on breaking up with me is because he hasn't felt this way about a girl since the last girl who really broke his heart and it is scaring him, but now he wants me to be by his side so I can help him through this. I believe his love for me is genuine and I love him too but I don't know if this is just a reason he convinced himself is the reason and he just wants to be with someone or he wants ME. I am finding it hard to trust him/feel betrayed and used now after he has broken my heart so many times but of course I want him back. What do I do?
