Can someone please help

Lately I’ve been getting these strange “certain feelings” and sensations whenever I think about my boyfriend or look at pictures and videos of him. Sometimes it feels bland, soft, watery, heavy, or like a weird warmth in my chest or throat. Sometimes I get a sudden jolt or an anxious “yes” feeling when my brain asks things like, “Do you have to let him go?” or “Do you really want to be with him?”One of the biggest sensations is this feeling that he isn’t mine anymore, he isn’t really here with me, or I’m losing him. It can happen really fast and feel extremely convincing. Then my brain starts saying things like, “You’re losing him,” “You don’t want to be with him anymore,” or “You have to let him go.” Sometimes I even get an anxious feeling that feels like a “yes” when I ask myself if I’m ready to let him go. The sensations feel very convincing, so I start wondering if they’re revealing what I actually want. I’ll think about my boyfriend and suddenly get a feeling like he isn’t really there with me anymore or like I’m losing him. Then my brain tells me I need to leave him or that he’s becoming a side character in my life. This scares me because I genuinely don’t want to lose him and the idea of letting him go makes me really sad. Sometimes I feel bland when I look at his pictures or videos, and then I start thinking, “Does this mean I don’t love him anymore?” Other times I’ll see him doing something cute or funny and naturally feel happy, warm, or think he’s adorable, but then I immediately question whether I forced that feeling. The hardest part is that the sensations can come very quickly and feel like they’re telling me what I want. I’ll ask myself, “Am I ready to let him go?” and get an anxious feeling that feels like “yes,” and then I get scared and wonder if I’m supposed to break up with him. I keep trying to figure out whether these sensations are actually telling me something or whether they’re just part of the intrusive-thought/OCD cycle.I’m exhausted because I just want to know what I genuinely want. I love and miss my boyfriend and want him in my life, but these sensations make me question whether that is genuine. I’m scared that one of these feelings means I have to let him go, even though I don’t feel like I want to lose him.
