Last year around this time, nahuli ko c bf of almost 3 years na communicating with his ex/bestfriend in one.
He was driving when his phone alerted a notification na message received with the name of his ex gf. So I was shocked at first kase I didn't know that they were on speaking terms. At first I didn't react pero later that night, I calmly asked him why he and the ex were communicating. He was shocked that I knew based on his reaction and I think around that time if I hadn't mentioned na I knew, he wouldn't have bothered to tell me. I wasn't initially jealous naman, more on shocked lang pero of course there was this nagging feeling na why were they talking after so many years. I wasn't able to read their conversation kase when I checked his phone deleted na the messages. I think that was the very first time na I doubted him. I never confronted him why the messages were deleted but I made sure to have it known na I wasn't comfortable with him talking to his ex. Mind you, this was the same ex/bestfriend na he almost married and he was willing to adopt pa the ex's son from another guy. Plus, that time, bf was in a relationship with another girl pa, tapos iniwan niya the other girl and chose this ex over the gf at that time.
In short they have deep deep history together. He would assure me naman from time to time na close lang sila and they were bestfriends first before anything else. Naloka lang ako kase after years of no commu between them, nung nagusap sila biglang close na sila agad na parang wala nangyare sa kanila

Mega kwento pa tong ex niya about sa lovelife niya, kesyo break na sila nung current bf niya kase ganito ganyan. Seriously?
Overtime I became passive about it kase I brought it up with bf a couple of times na I'm not comfortbale with them talking but he brushed it aside and ni hindi gumawa ng way man lang para iwasan si girl. I mean they viber, imsg , wattsapp, fb, tweet and even facetime each other. WTH
Before nahahawakan ko yung phone ni bf and he wouldn't mind me reading his inbox so ayun one time I read their full conversation tapos there were flirty replies from the girl such as 'ikaw muna stand in bf ko' , 'may sasabihin pala ako sayo paguwi mo' or 'i love you bes'. It was so inappropriate at the same time so disrespectful to me. I was so pissed I slammed his phone on the table (we were in a cafe) and looked at him straight then I ignored him the entire night. I think I ignored him for a few days after that and he had resulted into making lambing such as giving me flowers and hand written apology letters and assured me na they are best friends lang daw talaga

Wala naman nagbago sa ugali ni bf, he's still the same as before yun lang, there's a part of me na nawala yung full trust ko sa kanya. Before I would really get pissed when I read their convo pero now I don't go out of my way na. I let him talk to her, I don't complain. He hasn't heard from me for months kaya siguro I became passive about it. Yung girl added me pa sa ig and fb and would like my pics and all. Minsan I would make jabs na 'oh kumusta na landian niyo ng best mo?' and he would just look at me and say 'hindi kame naglalandian', I just shrugged it off. Last basa ko na convo nagbabalak ang girl makifriends friends with me, I pointedly told bf I don't want to be friends with her.
The nerve ng ex niya maki-friends, nalaman ko when bf and I had a big fight about something else, it slipped out sa argument niya na 'kaya ayaw sayo ni (insert name ng ex). I was shocked and then bf made kwneto nung nagcalm down na sya, ayun nalaman ko nung kakastart lang nila nagreconnect last year, yung ex was telling my bf na she doesn't like me for bf daw kase plastic daw ako

I was like WTF? Ni hi - hello nga never kame nag-exchange tapos sasabihan niya ako ng platic? HAHAHA!

Nakwento ko sa friends ko yan (one of those personally knows the ex) and we were laughing about it, I said 'ano ngayon kung ayaw niya saken, anong pake ko, I don't need to please her plus pano niya nalaman plastic ako? close kame? Ni isang sentence nga never kame nag-exchange hahaha!
So ayun to cut the story short, they still communicate till now, pero when I get a hold on bf's phone delated na messages. I don't ask or pry anymore pero I keep in mind na mahuli ko lang si girl na talking bad about me with bf silently agreeing or going tango behind my back, aba, I walk away. I always tell him na pag ayaw niya na, sabihin niya lang kase I will not subject myself into begging nor being with someone who doesn't want me anymore:

So far, we haven't spoken about her. Although mejo naiirita parin ako when her face flashes sa newsfeed ko. Feeling niya ang ganda ganda niya. Apprarently pag naguusap sila ni bf lage niya sinasabeng gandang ganda siya sa sarili niya

LOL NALANG! HAHAHAHA!
