Long story but BF has Had MH problems. I'm worried hes about to relapse into depression (he even said he was worried he was sliding towards depression again). He's finding day to day life more & more difficult. I'm finding him increasingly difficult to be around because, although I'm trying to help & support him the best I can, I have 2 dc of my own (he is separated with 2 dc too). We have always got on so well, but he's had major issues (all before we met). I thought he was the one (we've both been married before), but as the days pass I feel like I'm losing him. It's breaking my heart & I feel so helpless. Should I call it quits before I get drawn in any further? Been together for 18 months. Any advice much appreciated as I feel so sad tonight. Thanks in advance.
