(19F) - My boyfriend (22M) is acting immature and exhibiting toxic behavior.

Hi, I (19F) am seeking advice regarding my relationship with my boyfriend (22M). I’m starting to feel that he’s immature, manipulative, and doesn’t respect my boundaries. We met online shortly after I ended a mentally draining situationship, and things progressed rapidly. Even before we officially started dating, he requested explicit photos and sent me sexual outfit ideas. Eventually, we transitioned into a friends-with-benefits arrangement, and after a few months, we both admitted our feelings. I initially believed he genuinely cared for me, but now I recognize that I overlooked several red flags. Once we began dating, his friend purchased my ticket to visit him in another country. He didn’t contribute to my travel costs, even though I was flying alone to a new continent for him. I kept hoping he would demonstrate more effort, but it feels as though I’m the only one making sacrifices. He frequently engages in sexual conversations, especially about how we will be intimate when we move in together. I’ve shared my history of sexual abuse with him, but he continues to bring it up and reacts negatively when I’m not interested, saying things like, “You don’t want me” or “You’re not attracted to me.” This feels manipulative and dismissive of my feelings. During arguments, he gives me the silent treatment, despite knowing I dislike it because my father does the same. Instead of addressing issues, he simply acts as if everything is fine afterward, leaving me feeling confused and hurt. Financially, I’ve sent him over $700, even before we started dating, and he has yet to repay me or indicate that he intends to. He often asks for money for his debts or wants, despite having a job, and I lack trust in his financial habits. He tends to overspend on unnecessary items and seems to ignore future planning while frequently talking about us moving in together. Moreover, he is emotionally exhausting. He often says things like, “You hate me,” “I’m a bad boyfriend,” or jokingly mentions breaking up, which makes me feel guilty and insecure. I’m beginning to suspect that he may be manipulative and unhealthy for me, but I’m unsure if I’m overreacting. Should I try to work through these issues or consider ending the relationship? I would appreciate any advice.
