She came again... in Dreams

Last night I had another dream about BL. (First GF.) I seem to do really good for a while, where she isn’t on my mind, I don’t dream about her, nothing makes me think of her, then boom, there she is, in living colour.
Fair warning, I’m gonna be a bit explicit, so this may not be the best version of me to read.
Added info, my dreams come complete with internal monologue and foreknowledge. Not sure if anyone else has that in dreams, but there ya go.
We were here, at my house, on the couch, and things were getting heated - in the fun way. Apparently she’d just recently told me that we were pregnant, and we were celebrating, and I was almost but not quite “in”. Either that or it’s been so long since I’ve had sex even my subconscious doesn’t remember what it’s like - which might not be a bad thing. There wasn’t much talking, there were lots of smiles and kisses. Some details my subconscious hasn’t forgotten about her.
The last dream was 6 months ago and a similar situation, but it was closer to the beginning of the relationship, and given how long ago that was, the timeline is right for last night’s dream. That one, we were on her couch, making out, getting fairly frisky, we were pretty well tangled up, I’d just gotten her bra unhooked when her mom walked into the room. Oddly, BL just laughed and goes “Mom! We’re kinda busy!!” Her mom starts laughing and goes “Oh brother! Sorry!” and starts laughing as she walked out. Then, of course, BL and I went back to what we were doing, me being more embarrassed and her really not giving a crap.
I don’t know why my mind seems to love to torture me with her. I mean, at least it’s not as frequently as what I was having with “The Ginger”, but because of who she is and what she was to me, I’d swear this is more torture when it’s BL. Now I won’t stop being able to think about her for several days. Just when I thought I was getting a handle on this shit, and was able to get on without having BL or The Ginger in my head making me trip all over myself, but no… no.. that’s not what I get. How am I supposed to be able to date anyone else with either one of them screwing me up?
I was talking to someone as of recently, and I was liking where it was going. Guess I’m gonna slow that down to a stall for now. I’ve got to get these two out of my mind so I can properly get on with my life. I just have no idea how to have that kinda control over my subconscious. Really wish I had a delete button. I learned a lot of good from BL, but sometimes it’s near impossible to get on with life when she gets dropped like an atom bomb back into my head. Thing is, even if she showed up here today, proclaimed her love for me, and threw herself at me, I couldn’t take her, cause as bad as I fucked up with her back then, there’s no way I could keep her now, and if I can’t keep her, then what’s the fucking point?
Time to get ready for bed and bend over for work tomorrow.
