bf cheated, now i feel like i over control him

Problem/Goal: my bf cheated 2 mos ago, now i overthink like A LOTT, minsan nagcause na rin ng away. My jealousy became uncontrollable.

Context: for context, he installed dating apps and talked to a random girl and brought the conversation to his personal IG. I caught him isang araw palang ng pagcheat nya hahaha ewan ko ba lakas lang talaga ng pakiramdam ko nung araw na yun, kaya hiniram ko phone nya and ayaw nya ng ibigay. Which was every unsual kasi before nahihiram ko yun ng hindi sya nagrereact or what. So ayun, hule ko sya, nakausap ko rin yung girl and naconfirm ko. Kinonfront ko siya, like 2 days after i gave him a chance. I know some of you will say ang tanga pero mahal ko talaga sya. I can’t seem to let him go. Tho he promised na he won’t do it again. He gave me assurance. Tuwing umaalis siya nag-uupdate sya with pictures kasi he knows na magooverthink ako.
Therefore, i pushed my relationship to him. However, since that happened, hindi ko na maiwasan hindi magoverthink. Kapag late reply sya, iniisip ko may kinakausap na naman sya. Bigla kong hihiramin phone nya to check his soc meds. Umabot pa sa point na even his friends na babae pinagselosan ko na. Nilalagyan ko na ng meaning lahat ng actions nya. Nilimit ko na rin siya lumabas kasi nga nagseselos ako dun. And nag-napagawayan pa namin nung minsan magpaalam sya na bday nung kaibigan nyang babae tapos ayaw ko pumayag, parang hindi ba daw ako masaya na nakakasama nya friends nya. Bakit ang higpit ko na raw sakanya. Hawak ko na sya sa leeg. Pero in the end, pinayagan ko pa rin naman sya. Nag-uupdate and nagusap naman kami nun. Ayun lang talaga, while nasa relationship ako, wala akong peace of mind kahit nagbibigay sya assurance. Hindi ko alam kung kailan yung time na magiging umbothered na lang ako. Mapapagod rin siguro ako magoverthink noh? Hahahaha

Previous attempt/s: Every time na nagooverthink i always try icalm down sarili ko. Dinadivert attention ko sa ibang bagay. Im still in the process of healing, it hurts pero i made this decision. 😅
