LDR

This is bad

in addition i pay for all dates because she is a student .

This is bad too.

Now as things became more serious , i pay more attention to texts timelapse and i feel like my oneitis is creeping in.

Yep. When she's exclusive, it all matters. You become less attractive because you care more.

I tracked her ovulation phase , it's those 3 days , and by coincidence she vanishes for 9 hours (Not working , not studying this week ) , and respond when she is at home (because her parents rarely let her sleep outside) , says she was with her sister shopping , a female friend visited her and they went out and tries to keep the conversation with affection , emojis etc , good night .... I dind't buy this shit and the paranoia began AWALT.

Yep - sus.

Adding to that , she said she will send me nudes to recharge me for the next time we will meet , and she didn't (I didn't ask for them or said anything) .

"to recharge me" is a bit weird.

Broken promises is a very bad sign my dude.

To be honest i didn't sleep well 3 days in a row , i keep my sanity by running every night . I am really sure in my deepest guts this bitch is cheating (There can be no coincidence of vanishing and her ovulatory phase without cheating , the problem is i don't have a proof .... LDR ) . My dread is on point , minimal affection , coldness after thoses vanishes , she tries to keep conversations , double texts etc ....

You dread is not on point if she's not scared to lose you.

I took a decision that i will end this mess , keep lifting and work on my career . Honestly i can't plate her , oneitis is creeping in , to restore my plates i need time , and if i open the relationship , i will be more hurt (Seems like she has many backups she is actually cheating with) .

I think this is the right call.

You don't feel you trust her, therefore you should not have a relationship with her.

It doesn't matter whether she cheats or not...... you can't trust her....... doesn't matter if the fault is with her or you...... you can't trust her..... therefore on relationship

Now , we arranged to see each other the next week (she will come to my city) to stay together for valentines and her birthday .

ok...... but you're paying, and vday is a massive commitment.....

So i prepared a revenge plan (Beta trait but that will appease me at least ) , i will fuck her one last time , have good time , lovebomb her , do all naughty things i think of , then when i drop her at the train station i will send this message to: Hey babe , i think this long distance thing won't work , it's better to stop it now . Wish you all the best / Then go ghost without closure .

This is FUCKED UP.

What do you think guys of my paranoia and if it's justified and my revenge plan .

Your revenge plan is fucked up.

You guidance and advices are very well appreciated .

Dude.... do what you want..... live your life.... prioritise yourself...... but this revenge plan based on a hunch? This is terrible.
