I know putting my business out here for the world to know can bring trolls but I have no friends and no family well I'll get to the point because it's simple really I cought my boyfriend cheating for the second time first time I had a sneaking suspicion but no proof until I downloaded messenger 2 days before my 1 year anniversary boom him talking about going to have sex I gave him another chance he started with the same sneaky hiding the phone behavior again I was like then the other day he got to comfortable I snuck up behind him sitting in his recliner and watched him click away in his phone like he knew where is was seeing him looking at womans crotch responding to them and him erasing shit I'm like "I cought you stupid" he said it was old he wasn't doing anything please keep talking I don't know what to do I'm disabled no income no family no friends I feel alone and lost I've done nothing but a good woman to him
